Everglades, Week One, Awesome.

Posted on by Katya Posted in electrical, National Park, out and about, RV life, survival, travel | 1 Comment

After staying on the west coast of Florida for over a month, we were happy to finally find a place in the Everglades that allowed RVs. Long Pine Keys campground is the first campground in the Everglades one of only 2 that accept RV’s. The other campsites are only accessible by canoe, which makes them even more awesome, but sadly out of our reach. As you can imagine, Long Pine Key is a forest of really tall pine trees, mostly bald, which become excellent bird perches when dead and have provided me with plenty of awesome bird photos ( vultures, hawks and crows being my favorites).

There is no electricity or water here, but with Ross’s electric setup, and new improvements, there is hardly a difference. We use a gallon of gasoline a day for the generator which, most of the time, we can barely hear, even though it’s directly below our seats while we work. Water we have to collect daily in a 6 gallon tank, of which we use about one a day, and getting rid of the water, we do every other day with our tote tank, which we tow with the truck to a dump station. We use the public bathroom that is about 30 yards away most of the time, showers are the only water usage issue we have but its worth dealing with to stay here.

Besides TV, which we never have any good channels of anyway, we don’t miss out on anything. We have internet, can watch movies, use our laptops, use all the lights and of course the fridge and stove are propane. I could do this forever and not mind it really. During the day it can get pretty hot still of course, and theres not enough power for AC. It usually in the mid 80s so we have the windows open all day and a fan in the door, but about 3pm it becomes too warm inside and we all move our work to the tent outside (the size of a bedroom with a 6 foot roof).

We have basically been alone in the park since we got here last Sunday morning with just a few tents showing up here and there. This weekend though we were a bit bombarded with huge families who talked and yelled half the night and/or blasted their stereos, counter productive to camping I thought but in general, whatever, didn’t keep me awake.

We finally got to take a look around the everglades this weekend, and Friday night had been cold and the day started out really cool, so we felt we could leave the animals for a few hours with a fan in the window.  Our goal being Flamingo, the farthest south point in the Everglades and I think mainland Florida, and on the way we stopped at every turnoff we could find. Most of them were also occupied by tourists and people from nearby in blue mustangs (and other soft top mustangs), we went on a couple 1/2 mile hikes, one really amazing one through a Mahogany Hammock (a Hammock is a small forest in the swamp basically). The landscape in the Hammock changed so completely it was like going from desert to jungle in 5 steps. There were vines and old growth, strangler figs, woodpeckers, giant mahoganies, termites, ferns and everything you would expect to see in some kind of a rain forest. Outside of the Hammocks were miles of grassland looking marshes, most of which were actually part of a huge 8 mile wide, super shallow, river, scattered in some areas of the park were bald cypress and other parts, palm trees, or like the area we are in, long pines. Randomly throughout, there are deeper rivers, lakes and ponds filled with alligators. In the most southern areas, you might even find American Crocodiles and – if your in the water, dolphins and manatees. The whole Everglades is just a phenomenal example of varying ecosystems in one area.

There were canoe rentals at a couple points but without knowing before hand, we weren’t really prepared (maybe next weekend), as both of our canoe trips have been about 4 hours each. When we finally made it to Flamingo, we saw the campsites there, fairly open and busy but still pretty cool. The visitor center was abandoned though not in too terrible shape, having closed after Katrina damage. By the time we got there we were starving, half expecting a restaurant or store but finding a small marina shop, with a pretty terrible selection of snacks and sandwiches for fishermen. We bought enough to get us home, walked around a bit and headed back to camp.

We stopped off at the end of a dirt road we saw on the way, partially flooded and gladly tourist free. It lead to a small pond that kept a couple alligators, one at least 8 feet, and as we later found out, a Water Moccasin, which as the time we did not know the identity of.. and poked with a stick because we thought it was dead. It was just shedding and busy, and probably cold, so we got lucky he was feeling nice that day.

We weren’t sure about staying here without electricity at first since a week would be our longest since last year at Slab City, but since it’s so incredibly easy and only improving, we’re staying another week. We would like to stay at Flamingo but not sure about internet, so we may just head there next Friday night and stay through Sunday night, heading to Shark Valley after that!

Off Grid Power

Posted on by Ross Posted in electrical, projects | 2 Comments

I wasn’t sure what we were going to need to be able to power ourselves while totally off the grid.  I read as much as I could and I thought I knew what equipment we were going to need.  But when it came down to buying things, I found there were too many choices and too many gaps in my knowledge of what we needed – like, what gauge wire should I be using to run from the battery bank to the inverter?  No clue.  Apparently not having a clue about this stuff is common enough, because most of the online companies selling this equipment have helpful sales people who will work through what you need based on the amount of power you expect to be using per day.  I made a call to one of these companies and had a really nice woman ask me tons of questions about the equipment we were going to be powering and for how long each day, finally promising to send me a list of equipment that would match our requirements.  But this list never showed up.  Awesome.  So, I picked another company, and went through the process again.  This time, the guy emailed me the list of equipment he recommended before I was even off the phone.  And here it is.

  • Go Power 1000 Watt True Sine Wave Power Inverter
  • Remote switch for Inverter (to monitor battery levels inside the RV and to control the inverter)
  • Inverter Install Kit – battery shunt, cables etc
  • Battery Charger
  • 4 Stage Battery Charger Module
  • Auto Isolator (to charge house batteries from alternator)

All this stuff is awesome, but it’s not going to be here until Wednesday – delaying us yet further, especially as I need to at least partially install things before we leave as we don’t know where we will be stopping.

We will get out of town..eventually.

Rain on the Windscreen

Posted on by Ross Posted in electrical, Mechanical | 2 Comments

When we got the RV, another one of the projects we had to work on was the windscreen wipers.  There were wiper arms,  something which may once have been wiper blades crumbling on the windscreen, a broken wiper motor and a few loose wires hanging behind the dash.  Exactly where the switch went I don’t know.

wipermotor

This was a fairly minor project.  We purchased a new wiper motor online, somehow only paying $5 for shipping.  No idea how companies price shipping.  Seems to be entirely arbitrary.  Anyway, fitting the new motor involved little more than removing a grill and and 4 bolts holding the old motor in place, and replacing it.  This was all great – I could wipe the windscreen clear any time I felt like tapping a wire on one of the battery terminals, but you can probably get a ticket if you try do that kind of thing while you’re driving.

3wayWiring the switch into the dash was a little more complicated.  Really we needed a 4-state switch – off, low speed, high speed and washer jets.  We opted to just get a 3-state switch, and forget low-speed mode.  The resistor required for low-speed operation was missing anyway, which is why you can see the two wires twisted together in front of the wiper motor.  I wasn’t responsible for this, and it’s a minor example of the lazy hack-jobs that have been done throughout the vehicle’s wiring.  Wiring the switch took a while of staring at the circuit diagrams in the maintenance manual to work out.  And despite being absolutely, mostly, fairly..somewhat sure I wired it right, the windscreen wipers don’t park themselves when the switch is set to the off position.  I’ll have to pull the switch and fix that, but at least for now, we can drive in the rain without having to guess where we are going.

Bring the Noise

Posted on by Ross Posted in electrical, RV life | Leave a comment

radio Life in the RV was going to be quiet and dull without any music.  When we bought the Brougham, there was a busted old Pioneer stereo mounted in the dash with various buttons and pieces of plastic missing.  And of course it did not turn on.

After pulling the existing stereo and looking around behind the dash, it was no surprise it didn’t turn on – wires once held together with electrical tape had long since fallen apart.  This included the positive power cable, which, for some reason, had been connected carelessly to part of the cigarette lighter wiring – despite the fact that there was an ‘accessory’ wiring connection 2 inches away.  When this cable’s electrical tape harness has fallen off, the cigarette lighter’s positive wiring had just been rattling around inside the dash, shorting out and blowing the fuse every time we replaced it.

To replace the stereo we picked up a Clarion unit at Frys – nothing fancy, but it sounds great, and, most importantly, has an aux input on the front for our mp3 players.  Installing the stereo was no work at all really, the only difficulty being slowly working through the speaker wires which ran to the dash from who knows where.  The factory stereo installed in the van back in ’73 was in fact a ‘mono’ – with a single speaker in the center of the dash.  A previous owner had installed a couple of small speakers – one on the ceiling between the seats in the cab, and one towards the back of the RV.  Somehow though, despite there being only 3 speakers I could find, enough wires for 5 speakers popped up behind the dash.  Hidden speakers in the shower?  Maybe.  And if not, I might just install some.

Aiwa SpeakersGiven that Katya and I both like our music loud enough to cause small earthquakes, these little speakers weren’t going to be enough.  Our budget was limited though – not enough to go all out and get amps, crossovers, subs and all the rest of the usual car audio stuff.  Instead we took a trip to our usual destination for picking up cheap things we need – Goodwill.  Conveniently, there were a couple of Aiwa home-stereo speakers recently divorced from their lifelong partner, and looking for a new one.  We plugged them into a random stereo, grabbed a Poison tape from Goodwill’s excellent tape selection, and turned it up.  They sounded pretty great.

After peeling back the rubber flooring in the cab, inhaling a significant amount of whatever weird insulation material is under there, and running new wires, our speakers were installed out of the way behind the seats.  I also wired up the smaller speaker on the ceiling of the cab to provide a little fill.  For now this works.  If I was incredibly anal about it all, I’d probably be bothered by the fact that these speakers don’t really match the output impedance of the stereo’s amp, their current position means a lot of the higher frequencies a dampened by the seats…  I just realized that apparently I am incredibly anal about all of this, and it does bother me.  Silly thing about that is – it really does sound great the way it is.

My next project will be to install a power switch for the stereo so we can run it off either the starter battery, the house battery, or the converter box (the box that allows us to plug into external power sources, like at RV parks).  As well as the power switch, I’ll be running some wiring from the cab over to the living area of the RV so we can connect our laptops to the main stereo and enjoy music and movies through something other than feeble little laptop speakers.  Conveniently, the stereo came with a little remote control, so we won’t even need to get up to change the volume.

And after all that work, while I’m still back in Portland, working through selling the rest of my belongings and re-homing my cats, I’m stuck listening to music through my computer’s speakers.  Guess that’s what I get for not having sorted all this out sooner.

Why won’t it start?!

Posted on by Ross Posted in electrical | Leave a comment

The Brougham really is in pretty great shape mechanically, considering it’s age.  The shocks are shot – but what can you expect for a vehicle that size of that age, and they are easily replaced.  The carburetor needs rebuilt, but, again, it’s a relatively small task.  If I knew a little more I’d buy a carb rebuilt kit and do it myself.

The first major task I have been able to tackle has been the wiring.  Life in the northwest did a number on the wiring connections – all of them are coated in rust – and custom wiring jobs done by someone who was clearly completely insane haven’t helped either.

We started out on our first real trip – to Spokane – with the needle on the fuel gauge close to empty, not sure if it was right or not, and had to pull off the freeway to get some gas, only to find the vehicle wouldn’t start again.  Not a great situation to be in in the middle of the night.  All of Katya’s possessions were loaded up in there and we were a long way, and an expensive tow, from anywhere we wanted to be.

We knew it was either a problem internal to the starter, or the wiring, but were unsure where to start with determining the cause.  Luckily an awesome guy named Gordon, whose truck was parked in the truckers’ lot next to the gas station, saw us puzzling over what to do.  He came over, poked around under the hood, listened to the solenoid switching, and, when I mentioned that occasionally I’d see sparks on the connector terminals when I tried to start it, he grunted, asked for a screwdriver and disappeared under the vehicle.  Seconds later, the starter was spinning.  Turns out the issue was nothing more than extremely corroded, rusted wiring at the starter terminals.  I grabbed a socket set and some sandpaper and cleaned up the wiring and the connectors.  Thanks to Gordon we were on our way again.

We had one other issue with starting the vehicle.  Occasionally, we would turn the key..and get nothing.  No clicks, nothing.  After a while we found that shifting back and forth between park, drive and neutral we could eventually get it to start, usually when in neutral.  After hunting through the repair manual I finally found where the park/neutral/reverse signal comes off of the transmission – providing an indication to the start relay that the vehicle is in park or neutral, and turns the reverse lights on.

Like many of the other problems, we guessed that it was likely caused by wire corrosion, so I set to cleaning them up.  The transmission end of the wiring was coated in what must have been at least a quarter of an inch of oil and dirt, which took forever to clean off enough that I could check the connections.  Of course, after all that, that end of the wiring was perfect, having been protected by a water (and oil) tight rubber cap.  The wiring connectors at the starter relay weren’t so lucky – they were pretty well rusted.  After cleaning them off, we haven’t seen the same problem again.

So, our starting problems are gone – now we just need the carburetor rebuild and some repairs to the exhaust system, and we’ll be able to keep the Brougham running once he’s started too.
