https://www.xjbikes.com/forums/threads/xj650rj-seca-build.111444/ This is the thread for my build of my 82 xj650rj seca. I have a custom wiring harness using a MotoGadget m-unit. wiring diagram below. I've had the bike working 100% electronically for over the last year. The other day, I was trying to start up the bike and while holding the starter button for around 5 seconds, suddenly it stopped cranking. Here is a list of my diagnosis afterwards. I'm looking for feedback on what could be the culprit to help me focus my efforts. All of my testing/diagnosis has been with the power-on, bike off. - headlight bulb appears to have blown (hooking the headlight directly up to the battery yields no light - starter solenoid appears to have died (a new one has been purchased to replace) - My starter appears to be bad. I can currently in the process of waiting for a rebuild kit and will go through it per the write-up on this site to ensure that everything is good. I suspect that it will need new brushes, as when I took it apart to inspect, the brushes looked very worn down. - when having the reg/rec & the brown and green AC Gen cables hooked up at the same time, there appears to be some short occurring which causes the MotoGadget m-unit, and my speedo gauge to very quickly flash on & off. (either due to a ground, or a positive charge issue. I'm not 100% sure which). When unplugging 1 of them, all lights work on the bike. Any recommendations on where to focus my diagnosis on? My thought was that either I fried the Reg/Rec, but I didn't think that it really "kicked in" unless the bike was on and running. Or did I mess up my AC Generator?
