Tow vehicle isn't charging trailer...weird one...
Ok, this is very strange. Originally, my tow vehicle was a 2006 Toyota Sequoia. I had decided it was a bit anemic for pulling my 23" toy hauler. I have since sold it, and purchased a 3/4 ton suburban 2500.
Unfortunately, starting in 07 Chevy doesnt wire their trucks to be fully tow compatible right out the gate. You have to fish out the wires for the charging circuit and the brake controller circuit in the engine bay, and route them into the fuse box. From there, you have to fish the brake controller wires out from the dash, and you're in business. Not overall terrible, but just like...why?!?
Anyhow, my brake controller was already sort of set up as the PO of the vehicle had a crappy controller installed. I have since removed it and installed my Prodigy P3. Works great. My issue is the charging circuit.
I get 12V at the 2 oclock pole on the 7 pin connector on the truck. Also, I get 12V at the corresponding pole on the trailer side, presumably from the camper battery back feeding it. Everything worked fine on my sequoia...but it wont charge the battery here. Any thoughts on where to start? I'm going to check out the 40 amp fuse under the hood. It may be near failure where it can pass 12V, but no amps/load.
