Default 1982 Yamaha G1 not charging

Hello,
I am not charging on my G1. I have replaced voltage regulator and still only about 11 volts at full speed.
Can someone help me with this? Possibly generator? Or it needs new brushes.
I do not know the proper way to test these things on this cart & I do not have a wiring diagram.
Thanks

Here is a link to the full service manual which includes wiring diagrams:

This is a link that explains how to test a generator:

If you changed your VR already then there probably is something up with your starter / gen or associated wiring.

Cables going from your solenoids to your starter gen and from starter gen to battery are common issues on these as they are 30+ years old. The cable eds corrode which cause voltage drop. make sure to either clean, repair or replace these cables and ends. Also make sure your battery is actually good. Charge it and have a load tester put on it.
