I'm converting my 860 to 12 volt. Any feedback on my wiring diagram would be greatly appreciated. Thanks in advance.

Quoting Removed, click Modern View to see

hightech1953's circuit drawing is using an amp meter instead of a volt meter. An amp meter needs to be in series between the alternator and the battery to show the current, but a volt meter needs to be in parallel with the battery, so yours is correct for a volt meter.

I would use this method since it is proven.

Thank you. You have the alternator wire going to the key switch- I have it going to the hot side of the solenoid. Is my method an issue?

The neutral safety switch is doing nothing. It has to be in series with the start circuit.

The neutral safety switch is a push button grounding switch to engage the solenoid that will only push down with the transmission in neutral. He has it connected properly.

Your diagram doesn't show an actual ground cable from the battery

but I think that can be assumed. Voltmeter neg can go to chassis.

Assuming a 1 wire Delco alternator setup, the only other thing I
see at first glance is that I would use a 12V coil that doesn't

require an external resistor (NAPA IC14SB or equivalent) and
eliminate the resistor. Less connections, less corrosion, less problems.

Thank u. Yes I have battery grounded to chassis as well as neg. on volt meter. I used 6v coil because I had it in stock.

Changed my 640 over to 12 volt last fall. Read alot about the 2 different types of alternators and decided to go with the 3 wire over the single wire. My understanding is the 3 wire will charge at pretty much any RPM. Whereas the single wire needs to be revved past 1700 RPM (or so) to initiate its charging circuit every time the motor is started.

Please chime in if my info is incorrect.
