67 charging problems

[2talljack]

A buddy of mine picked up a 67 fl. It is stock.He is having charging problems. I have a twin cam and an 86 evo, but am not familiar with this system.What should we look for and  what is the correct way to test it.We have put a full charge in the battery. Does any one have a wiring diagram for it.    Thanks

You need to make sure that you polarize the generator on those bikes

What is the right way to polarize.Do we ground f and then + to A on the generator?

Briefly  touching a jumper wire between "Bat" terminal and "Gen" terminal on the regulator before starting the engine and having all the connections where they belong will polarize the generator.

 Just buy a cycle Electric GV-5000 generator and  electronic regulator ,you will be good to go for a long time ,No polarization needed, made in USA , The original equipment supplier to Harley...Mule...
