Okay, incredibly intelligent friends, I have an electrical riddle for you. Need some ignition help. We put a new wiring harness on our GL 500. Wired up the ignition circuit and hit the starter button and the starter turned over, so we called it a day. The next chance we had to work on the bike, hit the starter button and nothing happened. We hadn’t changed anything. We’ve traced everything. Power is going to the solenoid (which is brand new), but it’s not tripping to pass juice to the starter. We replaced the solenoid and still nothing. We took the starter off and went straight from the battery to the starter and the starter turns just fine. We took both solenoids and put them on another bike and they work just fine. We’ve traced connectivity through out the system and all of the grounds are good. We even replaced the plug on the solenoid and put a brand new starter switch on. In desperation we took the wrap off the wiring harness and inspected every inch of the wires. When you hit the switch, electricity makes it to the functioning solenoid, but doesn’t make it to the starter. Battery is fully charged. I’ve run out of ideas. Any thoughts? It seems like physics is failing.
