I've got the same problem! Went to start my helios today(despite the cold start issue; work in progress) and the motor would hardly turn over. Jumped it and didn't make a difference, battery still had no power almost like I wasn't even jumping it. Then I get a little puff of smoke from the clamshell area on the column so I start pulling everything apart and I find this:
I'm still in the middle of tearing everything apart, just wondering if there was ever a resolution to the problem here. Any help would be GREAT.
