1983 R80RT - Diode Board Fried?
1983 R80RT - Diode Board Fried?
I am guessing I fried the diode board - is there a way to test it without taking the front engine cover off and removing the board? My mechanical skills are fairly good - electrical, not so much, but my brother is nearby who is better at electric.
Hoping for some guidance, and thank you!

There are tests that can be done of the charging system without taking the diode board out but you will need to remove the front engine cover. On the RT, that does mean the front fairing cover.
There's a lot to take in here, but Snowbum has a page on his site for troubleshooting the charging system:

The Classic Boxer Charging System is a good book to have:

Before reconnecting the battery, I removed the tank again and disconnected the wire on the starter solenoid that goes to the diode board since it seemed to be causing the short. In an effort to confirm that was the problem, I connected the battery and just hit the start button to make sure the starter worked and it did. I didn't attempt to actually start the bike since the gas tank is off, but at least I knew the starter was working.
I've read lots of articles suggested by you and also here in the forums. A lot of them are over my head but occasionally I pick up a tidbit that is helpful. I appreciate the guidance.
