Ok did some digging, I apologize for the misinformation previously stated. The large white wire runs from the 80A engine fuse, around the front of the radiator and was connected to the terminal marked "A" on the isolator, no splicing. By the terminal "CB" I meant "Coach Battery" so I'm pretty sure that was wired right. The 3 wires coming off the plug on the alternator are unmolested and run to a factory loom. I'm just hung up on why there was a "bubba" run wire from the top nut of isolator to 12v positive. It should really be a switched 12v source , correct? So would the switched 12v source wire be one of the 3 wires coming out of the Alternator plug?

Thank you for your quick response! These are the wires off the bottom of the alternator. The thick white wire that is 12v constant (under my thumb) is the one that was connected to the "A" terminal on the solenoid. Should I probe the other 4 wires (yellow, red, black, and thinner white) to see which one is 12v source? Also, is it redundant to have both the 12v constant white wire and the wire directly to battery on the same post since they are both 12v constant? Thank you!

1986 Sunrader 22RE. This is the way my solenoid was wired up. Is this the correct wiring setup for the solenoid? "+" goes straight to engine battery, "A" is connected to 12v hot (constant) thick white wire spliced off bottom of alternator harness, "CB" runs to coach battery through 30A breaker. Also, top lug of Alternator has a wire that runs directly to positive terminal on engine battery. Thanks!
