Hello all,
It's been about a year since I originally posted a thread regarding my charging issues with my 750 Supersport. Long story short, I thought I had fixed the issue with a new charging system, rode it for another ~2 months before finally putting the bike away in early December. The bike started without hesitation the 2-3 times I went out and started it over the winter, though I finally found myself with a dead battery when I went to pull it out for a ride in late January (Cue new battery #2. Didn't have time to charge #1 before leaving). Rode it on and off (~400 miles total) until it finally lost battery power again on May 1st while on my way to work (got to the point of only having enough voltage to power one coil/2 cylinders). Threw another battery in it later that day and rode it home (new battery#3).
2 months later, the bike is still sitting. I thought it might be a bad connection between my new stator and regulator, so I fixed the pin that appeared to be not seating correctly, and put about ~50 miles on it with a freshly charged battery. Went out the following night and it was, again, dead. Now, I can only assume I have a massive current draw somewhere that's being affected by ambient temperature. A few days ago I read something about a bad solenoid switch/relay sending excess voltage to the spark units, heating them up, which may cause some of the black epoxy leaking out onto the battery (didn't think anything of it before).
So... Now my question is, before I spend the time and money to replace literally every electronic component and wiring harness in the bike, is it feasible that replacing the solenoid switch, solenoid relay, and spark units might fix the issue? The bike seems to run perfectly fine aside from this one (major) issue.
Thanks in advance!
What I've replaced so far: Stator, rotor, regulator, battery (AGM, x3), accessory fuses, main fuse.
