I have a power master alt that had a bad regulator so I bought a rebuild kit and rebuilt it. I have a lower amp alt on the car now but the power master is chrome so I'd like to use it. The issue is when I rebuilt it I bough a one wire alt conversion kit and that is what I put in it. I already have the 3 wire alt wired so what would happen if i wired the one wire the same as the 3 this way if needed I could switch back if something happened?
If it's really a 1 wire alternator, it only has one wire connection, so you can't plug in the plug. But if there's a place to plug in the plug, then plug it in, and see what the idiot light does (if it has one)
I've hooked up a number of them like this. The diode in the wire to the ignition switch is to keep the alternator from feeding back to the ignition and keeping the engine running. You can wire an idiot light into it as that is how the factory did it. It's simple and you know if you hooked it up wrong because the engine won't shut off until you pull the coil wire. I got the diode from the Massey Ferguson tractor dealer but you can find them at a Radio shack if you can find one or amazon sells packs of them for 7 bucks including shipping.
I have my 3 wire wired like that What would happen if I added the one wire with the same wires connected?
Or you can wire it to the accessory side of the switch with out the diode so it can't back feed the ignition.
