Most of the 1 wire Alts Wont Excite untill you get The RPM above 2000 rpm. Then they will keep charging even at an Idle.

Make sure your grounds are all solid. Alt case to block (anodize, paint, powder coat are all insulators). Block to battery.

Run an ohm meter from the alt case to the neg bat terminal to make sure you have good ground. Should be zero or damn close to it.

Did that, 0 on the ohm. I also have a two wire plug in the shape of a T, how can i manually excite the alternator? The 2 wire connectoer isnt mark with anything, would one of those excite it if i put power to it?

Describe the circuit from alternator output terminal back to the battery positive terminal.

Have you verified that even with the key off, you have battery voltage available at the alternator?
