I must confess electrical issues are somewhat of a black box to me...
So having said that my question Vic can you explain the wiring from your alternator to your camper?
When I bought my new truck I had our local truck accessory dealer to install a 7 pin switch in the left front side of the bed which is what Hallmark did on our original installation. I have no idea what gauge wire they used or where they ran the wire to..
Any insight would be appreciated....
Eddie...
Since we have near identical trucks...
I ran 2 AWG from Pos/Neg terminals of the LH battery, through a breaker for Red, back to camper bed. I used Anderson PowerPole on truck bed side to camper side. Camper side, Red cable ran through the Blue Sea 7622 separator, the other to the Blue Sea 500A shunt.
The heavier the cable you use, the more amps that can be pushed to the camper batteries from the alternator,
Once "bulk" charging is complete, it becomes a much slower process for Volts to push Amps into the batteries through absorption. The bigger diameter the wire the better.
I used tinned crimped 3/8" fittings on the end of the welding cable for terminal connections.
Go with welding cable!!!! More, thinner strands of copper means more flexibility in the wire and more amps being pushed through the wire.
