Connect a jumper from the field terminal of the generator to ground. If it is now charging, the voltage regulator probably is defective. If it still is not charging, leave jumper from field to ground and connect a jumper from the arm terminal of the regulator to the bat terminal of the regulator. If it is now charging the regulator is probably defective. If these test prove negative, then you may have a defective generator.
Happy Motoring

If you know the battery is OK(no dead cells, etc)Check the belt to see if you can turn the generator by hand. If you can, tighten the belt.
Put a jumper wire between the ARM and FLD terminals of the generator. Start the engine and see if the ammeter shows a higher rate when the jumper wire is disconnected. If it does the generator is probably OK. If the reading doesn't change, the generator may be bad. Check all ellectrical connections, including grounds, making sure they are clean and tight. Check the VR. It's easy enough to pull the generator and take it to a generator shop or auto parts store for a bench test. My generator had a broken wire inside that cost $5.00 to fix.
