Tac, I have just one red wire on my alternator, attached next to the + sign as shown in the photo I posted of the alt. I am proposing to put a toggle rated for 20 amps at 125 volts which I think should be safe for around 200 amps at 12 volts where the isolator used to be, with the lead between the alternator and the toggle on one side and the two leads to the battery positives on the other. What do you think? Would that be a usable plan? My concern is that with the direct connection between the batteries and the alternator, I could see battery voltage at the alternator all the time, even with the engine shut down and the A-B switch in the off position.
