Below is question I sent to the techies at RT and I did'nt get the answer I was looking for.
I recently sent a question on the battery isolator hookup on my 1991 Dodge B250 Trek. RT's response was to tell me what the standard hookup is, which I already know. The problem is , I still don't know what the wire is thats comming out of the firewall that is green and turnes into black. The alternator output red wire is currently directly connected to the battery + connector. That red one should be connected to the middle terminal on the isolater. I dont know if that green-to-black wire is supposed to be connected to the primary battery side of the isolator no1 terminal. Seems like there has to be a wire connected to the engine positive terminal side of the primary battery.
I need to know what the green to black wire thats coming out of the firewall and where its supposed to be connected to. The puzzling thing is that it has current (its hot) with the motor off (no alternator) while it is not connected to anything.
Anybody that has a older 90's Treck may be able to help me.
Thanks,
