Re: chasis battery not charging; house battery cooked
See link below for pictures that show the state of the aux battery compartment and exisitng wires when we got the RV. There was no house battery in there at the time so I think things were "jumpered" together just to work off the chasis battery which of course was dead. https://drive.google.com/?tab=Xo&authuser=0#folders/0B0LyzXfPtA4RQVNYQ2dsbDE3ZUU218Views0likes0CommentsRe: chasis battery not charging; house battery cooked
Yes - it only happens when going down the road with nothing on. I have no generator and don't run anything inside while camping at this point. I have a sure power box with fins isolator with 3 prongs. When I got the RV - wires were already on the posts marked 2 and A so I left them. I connected the house battery (which was not installed when I bought it) onto post marked 1 as it was the only one empty. After the issues on the trip - I decided I woudld try connecting the opposite way - Chasis on 1 and house on 2 but the wires are not long enough to do that so I would "assume" that it was never connected that way. There were "jumper" wires connected when I got teh RV so could they have been jumpering posts 1 and 2 to accomplish proper connections? I will definately take the RV up to Pep Boys and have the altinator tested. In addition....I was thinking of purchasing a new isolator and new wiring and running it all new so I knew exactly what went to where without question. Parked with shore power everything is fine....If I don't run the fridge. I have a 3 way fridge that does not currently work on LP. I don't run it unless on shore power but it still seems to kill the battery - and oddly enough - the chasis battery, not the house battery which is confusing as it is wired directly to the house battery.218Views0likes0Commentschasis battery not charging; house battery cooked
1987 Holiday Rambler Class C - not in working condition when we got it. This was the first trip more than 30 minutes away - long enough for things to heat up. Starting point: New convertor with charge wizzard, existing isolator, new house battery and new chasis batteries. Was connected to shore power for 4 days prior to shoving off (with fridge on in elec mode) We set sail and about 2 hours into the 3.5 hour trip smelt a sulfur smell. Thought it was an exhasust problem. When we arrived at the campground, the house battery had boiled over and the chasis battery was completely dead. Matter of fact - the last 15 miles the RV choked off at every stoplight and we had to jump it every time. Once at camp... disconnected the house battery - filled it up and re-connected. Connected to shore power for 24 hours. House battery was at 12.4 v but chasis only at 9v. Day 3 - time to leave - chasis battery at 10v, house at 12.4. Made it from the campsite to the office to check out - choked out and would not start. Now stranded on a Sunday we went to the store and got a new chasis and house battery - installed both. Both started at 12.4v ish. Hit the road. Smelt same smell at 1.5 hour or so and pulled over and let everything cool off for 45 min. Engine then started right up - another 1 hour and we were home. Once home, went to check voltages - to my suprise - the new house battery had overcharged and had leaked! Any idea what could be causing this? Bad altenator? Bad Isloator? Connections wrong on isolator? I identified the convertor connections and they are plugged into the house battery properly. When on shore power - it is charging just fine. When we hit the road - something is over charging it. Have no idea how old the altenator is - could be original. Any suggestions on what to test or replace next?1.3KViews0likes7Comments
