Just put a new wiring harness on my 82 200e. Got it all rewired and hooked back up hit the electric start and it turned over. Didn’t crank because I don’t have the gas tank on. Put the gas tank on and hit the e start again and heard a pop in the back in. Did not try to turn over at all. Just a pop. Any ideas where to start? Solenoid? On the solenoid does it matter where you attach the black wire from the starter? And then The positive wire that runs to the fuse and positive terminal on the battery? There are two terminals on the solenoid so maybe I’ve got it hooked up wrong. I had a spare on my parts bike and attached it and it popped too. Ideas?
