I'm not sure if I ever heard this before, but when I went to check the minder on my battery, I noticed that the battery is actually making a sizzling sound, It is an AGM, so I'm kind of stumped about this. I am having issues with the starter jack possibly not engaging, and now I think I may have an electrical issue draining the battery and then making it sizzle during the tender re charge. Any ideas?

 

Sizzle on an AGM battery? Sounds more like a battery issue than a starter jack issue.

 

Sizzle? Remove the battery from the bike and get it checked out!

 

battery going south, goes toooo far, may go boooooom!
