Did you polarize your generator after installation? Has your voltage regulator been checked for proper operation?
Buying new parts and putting them on requires adjustments to get them to play nicely together. If not, the charging system won't work.
When I had my generator rebuilt, I also gave them the voltage regulator. I've tried to adjust the voltage regulator myself, one area I hope to learn more about as whatever I did, didn't work. When I got both my parts back from rebuilding, (place in So. MD near some guy I know down there) my Optima battery has been happy as a clam!
