I replaced my coach battery with two 6V golf cart batteries (from Costco).  The original battery probably had around 100AH, while the two 6V batteries have around 240AH.  I managed to put them side by side, so I think I actually gained a few inches of storage space behind the batteries.  Here's a write-up:

The van ('95) just started to do this 10 days ago.  I start it, it runs fine for about 5-15 seconds, then if I give it gas it doesn't rev (no power/doesn't move if in drive or reverse) seems to want to die, too much gas and it almost backfires, but rpm's don't go up and it struggles.  I baby it of 15-20 seconds and once I get it to rev a few times it's fine.  Drives fine until I turn it off and start it again.  Seems to be getting a little worse...it's died a couple of times lately, and not getting fine as fast after a few revs.

Seems like some computer version of a choke not working right, but my experience is with mechanical cars (like from the 60's).  My daily driver got totaled (I'm fine), so the EVC is now my daily driver.

Help…Any thoughts?

Winnebago "Full Campers" / Coach Battery Upgrade and Rewire Questions
« on: August 11, 2015, 12:32:12 am »
Just bought the car 6 weeks ago, the coach battery is not recharging while driving.  I'll put test numbers and symptoms below.  After some messing around I've decided to:
1) change the relay on the firewall above battery,
2) put in 2 golf cart batteries instead of single coach battery,
3) change the charger (either Progressive Dynamics [PD9245CV] 45 Amp Power Converter per David, or a ProMariner ProSport 20, 20amp, 2 Bank 43020). 

My main question is "Where is a switched connector (on/off with ignition switch) that I can attach the relay to." The relay in my car is not stock.  I believe the body of the stock relay was grounded to the firewall, and a 3rd wire was attached to a switched circuit.  In the picture below there is a purple wire that has been cut off (right arrow).  When the ignition is on it is hot, when the ignition is off it is grounded (or maybe I have that in reverse...).  I believe this is the wire that once went to the old relay, I know Winnabago used purple wires. 

If you take a look at the pic of the relay below, I believe that the relay put in by a PO is wrong or it's wired wrong.  It's a 3 wire relay, and is screwed in through plastic, so the body is not grounded.  The 3rd wire was hooked up to the neg terminal of the battery.  It's a voltage sensitive relay, It says on it: "cut in 13.7V, cut out 12.8V"  It was basically closed (current went through) no matter what.

Here's the symptoms and what I've found out, coach battery was dead (11.8V across contacts disconnected):
A) The relay: Engine on, engine off, coach battery connected or disconnected the relay stays closed (current goes through it).  The car battery died when not driven for 2 weeks.  I assume it was trying to charge the dead or dying coach battery while it sat.  Thus a new relay.
B) The charger works; 15+V if the house battery is disconnected, 13.8V with the battery connected.  Still, i'd rather have a smart charger.  Looks like an easy switch.
C) Coach battery was at 11.8V.  I charged it overnight on shore power, and it was up to 13.8, dropping .01 every few seconds when I disconnected a terminal.  Wanted to change out the battery for 2 6v golf cart batteries anyway.
D) Car battery is at 12.75V with house battery disconnected..

The parts I've ordered/purchased are:
-2 6V golf cart batteries from Costco
-Stinger SGP38 80-AMP Battery Isolator and Relay from Amazon.com
-Battery box: http://www.allbatterysalesandservice.com/browse.cfm/4,573.html
-2 of Camco 47440 Black 5/16" Stud 18" Long 4-Gauge Marine Battery Cable and Lug Assembly Tinned from Amazon
-E Support Car Battery Isolator Disconnect Cut OFF Power Kill Switch

Haven't ordered the charger yet, but I'll probably get the "Progressive Dynamics (PD9245CV) 45 Amp Power Converter with Charge Wizard" from Amazon for 168.99.

Share your adventures! / Advantures

Advanture to Gold Country in Northern California

Since this section is not just about pictures but adventures as well, I thought I might chronicle the first trip of my EVC.  I purchased it in early June, with a trip planned about a week later.  Two previous owners called her 'Millie' and it seemed to fit, so that's what we call her.

-A Slow Start-
In preparation, I brought it to a mechanic who had worked on my Vanagon in the past to get all the fluids replaced, check the brakes (the pedal seemed to depress too far) and change the timing belt.  One thing led to another and I didn't get it back until much $$$ and 3 days before the trip; new brakes, timing belt (was so old it was almost coming off the pulleys and had worn holes through the cover).  I picked it up, stopped at the tire place and got a new spare.

Finally I was ready to load the van, and went to put the tools under the bench seat….no storage??!?!  Under the seat was a solid black box.  After further investigation I noticed that the back of the box had two RCA connectors…a PO had taken out the storage and put in a base woofer speaker facing down.  I pulled to the seat, ripped out the speaker and built a storage box to replace it.  Then transferred the stuff from my Vanagon, plugged in the car and cooled down the fridge, packed up the family (son, GF and her daughter) and the next day we were off!

-The Heats On-
It was around 10 am on a sunny Los Angeles morning when we finally got out.  The weather was already getting pretty warm we headed north on the I5 up into the mountains toward the Tejon Pass and the San Joaquin Valley beyond.  Part of the trip up to the pass is a long 5% grade.  We were about half way up when I noticed the temperature light flashing and the gauge almost at the top   :o.  I slowed down, shifted into third and the temperature dropped incrementally, but enough for the temp light to stop flashing.  At 25-30 mph I was able to keep the temp barely in control.  Once we crested the grade the temp dropped, so though nervous, we bullied on.

As we headed north up the Central Valley, we found the AC wasn't keeping up.  Neither was the fridge.  I had bought a remote thermometer and we watched the temperature in the fridge slowly increase a degree at a time. 

In Fresno we stopped at a delightful Thai Restaurant.  Who knew?  My GF, Jill is a wonder at finding the best food places; the combination of her food karma and yelp makes for some good eaten'!  (see pic below)

Well, it was hot in the central valley, and it turns out the AC was not really blowing cold so we sweated the trip up to Jamestown.  I pulled into the nearest Walmart the next day and bought one of those canned recharge kits.  It worked, at least good enough for the rest of the trip.

-Dry Camping-
Onward and forward…We spent that night at the Jamestown Hotel then the next night at Tuttletown Recreation Area campground.  (pic below)  The campground is on the shores of New Melones Lake, a reservoir.  If you look at the pic below, you'll see that we were hardly on the edge of the lake.  In fact, it's down 250 ft, you can see it in the background, but it should have been about 20-50 feet from the campsite if full.  It really drove home the intensity of the drought we are having here in california. 

The battery died, and thus so did the fridge.  Not even enough power to start the propane, which kept blowing out from the wind.  We ate out most of the trip from there on.

-Disaster Strikes!-
After a few nights of camping, spelunking in a local cavern, and gold panning, we spent another night at the Jamestown hotel.  We got up in the morning to take a walk and I looked at 'Millie' and the rear tire was flat, plastic was laying all over the street, the side appeared to be dented and scuffed!  >:(  Some A*!#hole had hit the car.  (pic below) After looking closer and asking around I found that early in the morning some guy in a gold sedan had pulled out, hit my car and taken off.  It wasn't as bad as it looked, the plastic was the hubcap that was shattered, the scuff just a scuff, but he had hit the rear wheel and bent it thus the flat.  There was a scrape/dent near the front door, probably his rear view mirror.  I was so pissed that I just climbed under the car and changed the tire myself…didn't even think to call AAA.  It did get some of the adrenaline out.

-Off to Yosemite, no Stops-
So I checked that the rear axle wasn't bent, but all seemed to be in order.  We headed to Yosemite.  Nervous about the overheating I took it slow up the hills.  Felt like I was in my old split window or the Vanagon. If I kept it in third and under 3000 rpm all was well, it warmed up but stayed in the range.  That was about 30 mph or so.

Coming down into the valley I kept it in third, babying the brakes a bit, but obviously not enough.  They started squeaking when I braked.  Then the traffic stopped for photographers at a waterfall and I put on the brakes hard… :o….nothing…felt like the brakes had turned to glass.  The car did slowly stop, and since I kept plenty of space it stopped in time.  I smelled burning brakes, and the pedal now went down almost to the floor.  The traffic started and I did too, very gingerly.  The brakes started working and I started using 2nd for the downhill stretches, which I did for the rest of the trip. 

We just spent the day in Yosemite, ate lunch at the Awani Hotel, looked at some of the sites and ran away in terror at the numbers of people that crowded that beautiful valley.  Not at all like it was when I was 17, though it was crowded then too.

-Smooth Sailing Home-
Heading home all went well.  The AC now worked and I had mastered overheating prevention so going up the grapevine was not a problem.

-Wrap-up-
We actually had a good time amidst all the problems.  It turns out that one of the fans was not working which probably accounts of the overheating.  On the brakes, there is a controller that keeps the rear adjusted to the front.  It turns out a PO had messed with it and it was out of whack.  Thus I wasn't getting proper braking power on either the front of rear brakes.  Don't know about the charging, but it seems the system is charging properly.  I'll have to check the converter and the deep cycle battery is probably old.  It has not cutoff switch.

Overall, it was quite the advanturous trip.

Inline 5cyl Petrol engine tech / New EVC - what to service
« on: June 09, 2015, 01:38:31 am »
Just purchased a new '95 full camper (new to Eurovans, but have a Vanagon).  Drove it up from San Diego to Los Angeles and it drove great, even better after I filled it with 91 octane gas.  I had a mechanic look it over before I bought it, apart from some deteriorating rubber (including the spare tire), and some rust around the master cylinder and rear brake pistons it's in great shape.  He suggested I flush the brake fluid. 

I'm going on a trip with it on the 18th with my family, I was wondering if there is any maintenance that it is advisable to do.  I'm planning to:
-flush brake fluid
-flush automatic transmission fluid
-new spare tire

Anything else?  For a spare, do I need the expensive 100 load rated tire, or could I get away with a lighter cheaper tire to get me to a repair shop if I need to?

Thanks in advance!

Winnebago "Full Campers" / Interior Mods, Gadgets, or Additions
« on: June 08, 2015, 01:02:41 am »
New to the forum...although it looks like the forum is new too.  Good to see!

What kind of mods, gadgets or additions have you done to your Camper (or Weekender) to make it more workable?

I'm just buying a '95 Eurovan camper (tomorrow), and going to sell my '85 Vanagon weekender.  For the weekender I built a beautiful kitchen box (which I won't need in the new full camper), added a bench/drawer behind the passenger seat that the the box sits on, installed a second battery, made a front seat bed for my now 12 y.o. son.  I've been looking around for stuff people had built or modified on the interior of the Eurovan and apart from the GoWesty "Fridge elimination kit" I can't find a post showing a single homemade cabinet, shelf, alteration...anything!   :'(  With the Vanagon the is a plethora of things done to and with it.  I can't believe this is not true for Eurovans...we're the same creative group, aren't we?

So far, since I'll be leaving for a camping trip in 10 days, I'm looking to make a hammock for over the front seats before I go (that way the kids can sleep apart).  Here's a Vanagon idea on Samba that I like: http://www.thesamba.com/vw/forum/viewtopic.php?t=381648&start=20  I just have to see if it'll work with the window configuration in the Eurovan.  If not, I'll just put a board across the front seats which is what I did for my Vanagon

Anyway, I'd love to see some pics of what you people have done.
