'84 CX650E that is evolving into a GL500
This ^^^^^^^^ should have been the first thing you did.Mine did this as well when I first got it. I charged my battery and put it back in the bike and it started right up, but after a little riding the bike was dead again. Turns out a coil on my stator was bad and the battery wasn't charging. You might run the stator test if you're still having problems.
When Randall said your battery was questionable and your location didn't show when I moused over your avatar pic I assumed you were local to him and he knew about this issue off forum.
I have more time today so I looked up your IP address location (moderators can do that) and I see that you are not local to him.
If you had added your location to your profile as I asked you to do when you joined it would show when you mouse over your avatar pic and I would have suggested checking the stator last week.
