Hi Del-
It's AMPS more than VOLTS you want to watch.
Did you polarize the generator after all the new parts were added? Proper method is to keep the battery disconnected until last and wire everything up as it is shown in the diagram, then double, triple check the routing to ensure ALL wires are connected properly. Then connect a fully charged battery. BEFORE turning the key ON, polarize the generator at the VR with the simple arc/spark jumper method. Turn key ON but don't crank. As you do watch your AMMETER and you should see a slight needle movement/bounce for a second. Crank engine and observe needle swinging to "+" area of gauge. Once engine fires up, watch needle for movement to zero or plus side, like around 5-10 AMP mark. Let engine warm up a few minutes then switch on your headlights while watching needle on AMP gauge. Did needle swing to left of zero or zero? A bad battery won't hold a charge and you will notice a negative swing on gauge if so. Then the battery will eventually drain with or without lights on. You can take VR of and try tightening teh contacts too.

Thanks Tim, I have been using the A terminal on the generator to the negative terminal on the battery to polarize. Which two terminals do I use to polarize the generator to the VR? I am going to do as you say and disconnect the battery and re-check everything. I do not have the lights on it yet so will not be able to do that test.
