Just a chance, but check the condition of your master (dogbone) fuse. Remove it, check it for cracks, and reinstall it to be sure.

You might want to also check the condition of your grounding point (the point on the frame where the ground cable from the battery attaches).

Welcome to the site, J.W. If your stator is in good condition, it sould be putting out about 14.5 volts at 2500 rpm. As previously stated, you need to check the plug at the 3 yellow wires coming out of the stator at the left of the battery. If you don't have a Honda shop manual, do a search on how to check the stator and if it checks O.K. I would remove the plug and solder the yellow wires.

just an F.Y.I. The stator plug on the G.L.1200 is a weak point on the bikes charging system, The plug will get hot and then get corroded and if that happens it might burn out the stator, Like the other gentleman said it's a good idea to cut the plug out and solder the wires together (making sure that they are together right)
I had an 87 A and it is no fun replacing the stator

Also. How much electonics do you have running on the old girl? "radio, gps, Ipod..ect" and how many lights? They look great all lite up, but in town driving with all the lights on will not allow her to charge the batt back up. I found out the hard way. If all the other checks pan out and you use alot of lights and electronics, I would recomend the poorboy alt. system. I have heard it works great. I plan on putting it on my bike.

How many times do I have to tell ya,,, The right tool for the right job!
