Randy - Presuming you've wired it right and the ammeter is working, then the generator is not making enough current to carry the lights. A couple things to check: 1 - Are you doing your testing at max RPM? If not, try running the engine up to full throttle with the lights on. If the ammeter now shows 3 or 4 amps of charge, this is normal. If not..... 2 - With the engine running at maximum RPM and the lights on, take a jumper wire and connect the F terminal on the regulator to a good ground. If the ammeter now shows a few amps of charge, you need a new regulator. If nothing changes, the 3rd brush on the generator needs adjusting to boost output, or the generator is simply tired and needs a rebuild. To adjust the 3rd brush, remove the commutator band (dust band) from the rear of the generator. Now find the 3rd brush (that's the one without a mate directly opposite on the commutator). There's a small screw in the end frame that secures the 3rd brush holder. Loosen (but DON'T remove) this screw, then slide the brush holder closer to the other brush. Make sure there are a minimum of 3 commutator bars spacing between the two brushes, then tighten the clamping screw. The generator will now be set to maximum safe output. Post back what you find... Good luck! Bob M
