2005 Powertrek no power in the back

[Salehadel]

Hello, I bought 2005 chevy roadtrek, the generator is not working and the 1 Aux battery behind the wheel reads 8v , the one infront the rear wheel read 4V.

The monitor panel didnt read any power, assuming both batts are dead, can i have power in the back when the van is running from engine alternator?

Thanks

Yes, but why ask? Start the engine and see.

I did run the engine, still no power in the monitor panel at all.

With the batteries that low it is very possible they are taking more than the 50 amps that you likely have available due to the circuit breakers.


It is also very, very possible the breakers could have failed as they do fail regularly as the vans age. You would probably have one breaker under the hood and another in the rear, probably under the van near where the positive cables come together from the batteries.


Also very possible is that your isolator that allows charging to the rear to happen has failed.


Do you have any electrical testing skills? Have a multimeter?


It will probably take some testing to find out just what is going on and where you are losing the connection to the rear batteries.


You should take out the batteries and charge them individually off a bench charger to see if they are any good, which they probably aren't.

Thanks for reply, I think I would charge them or buy one new battery and test it. But my question is with engine running do i have to expect any power in the back? For example ceiling fan? Provide the batteries are dead?

I think I very thoroughly answered about what could keep you from having power in the back, so yes you should have power with the engine running, but all things I listed could and would prevent you from having it and would need to be checked.

I'll ask - can you contact the previous owner? Perhaps they installed a battery shut-off switch? These can be installed to isolate batteries when stored, or for security. Simple solution - if that is the case.

Best of luck.

Thanks everyone, i found an open 5amp fuse on the battery disconnect relay . Replaced and now it’s running perfect.
