Dave - Here’s a step-by-step that may help you figure out the problem:

1 – Make sure the ammeter is working: Turn on the lights with the engine stopped. The ammeter should indicate discharge. If it does not, either the ammeter is bad or else it is wired up wrong.

2 – Polarize the generator. With the engine stopped and the battery connected, momentarily jumper the BAT and GEN terminals at the cutout. You will get a small spark when contact is made. Soon as you see the spark you have successfully polarized.

3 – Now start the engine and run at ½ throttle or faster. If the ammeter shows no charge, run a temporary jumper wire from the generator F terminal to the grounded ammeter post. If the ammeter shows charge with the F terminal grounded, either there’s an open circuit in the wiring between the generator F terminal and the light switch or the light switch is not grounded. If the ammeter still shows no charge…

4 – With the engine still running at ½ speed, connect the BAT and GEN terminals at the cutout with a jumper wire. If the ammeter shows charge with the BAT and GEN terminals jumpered, either the cutout is bad or it is not properly grounded.

5 – If the ammeter STILL indicates no charge after doing the above, problem is in the generator.

Note – If the ammeter is not working and you have an accurate DC voltmeter you can determine whether the generator is charging: Take a voltmeter reading across the battery posts with the engine running at ½ throttle or faster. A reading higher than 6.6 volts says the generator is working.

Hope this helps!!
