Tom, the 2 that are wired together should be the 'house' batteries - for lights, etc. The isolator is to make sure a dead battery doesn't drain the other battery, so it sounds like the isolator is doing its job.

There should be a converter/charger system in place to charge the batteries when plugged into 110v, plus the alternator while driving down the road. If the batteries haven't been charged in a while....

i know how an isolator works, just unsure why it shows no voltage from the paired batts and on the center post and batt #2 post of the isolator show no volts either.

Do the batteries themselves show any voltage?

they werent have a charger on them. over on the firewall, right above the batt, there is a round piece that has 4 ga wire on both sides and a small center post. had no power on the left side and the center, when i put a jumper wire to the center post the left post showed power, the batts started to charge all the lights inside came on. the batt#2 on the isolator started to show power but the middle post is very weak,like 4 or 5 volts.

plus found another round relay looking thing on the motor that has 4 posts, 2 big 2 smaller. only 1 big ones has power other 3 are dead,it looks pretty crusty dont know if its bad.

Sounds like that round relay looking thing might be bad and there's something wrong with the other round piece - whether it's bad or a wire to it is bad.

Pace Arrow is now owned by Fleetwood. Apparently they have good records...

Email them (others have had good luck):

Okay, so it's probably on a P-30 chassis. I'll have a look around for that...

I can't blame you - that's essentially what we did on ours. The problem usually is that POs add to the electrical, 'fix' things....and make one heckuva mess  Roll Eyes
