    gr650 bobber project issues

    Hello,

    I haven't been on the forum for quite a while. Sold some GS bikes, aquired a couple Yamahas, and I continue to work a bit at a time on my gr650 bobber project. I've done a lot of work on this previously wrecked bike. I thought I had it pretty much finished until I took it for a little ride yesterday. Things were going well until just before I pulled in my drive way. The bike died, all electronics off and that was it. No fuses blown. However... something kept running inside the engine. Probably 5 minute after everything else had stopped. Sounded like the area of the starter. When I got it in the garage, I checked the head light, and it turned on... then as the thing keep whirling (kinda sounded like that) the headlight wouldn't turn on. I checked my battery for charge once the sound subsided. No charge. I hooked it up to the charger. It won't hold a charge.

    Any ideas? I was so... close.

      Sounds like the starter is stuck (solenoid, maybe?) AND the starter clutch is not engaging.

          That is what I was leaning toward. Thanks.

              Would the starter getting stuck because of solenoid problems total kill a battery? I know it was low in charge at the time of this happening. I also have experienced that if a battery drains all the way down then it won't accept a charge. Does all this seem reasonable.

              Thanks

                  Uhhh, yeah. The starter draws a LOT more power than the rest of the bike.

                  Did you ever notice the size of the wires that feed the starter?

                  Ever wonder why they are so large?

                      Got it. I've worked on several bikes but I'm finding that my knowledge of the electrical side of things is very weak, and needs work. Thank you for explaining.

                              The battery won't charge at all, or won't hold a charge once charged up?

                                  Won't charge. My charger... after a while said, check battery.

                                      The bobber lives! Now starter solenoid and battery and things are as they were before. I appreciate the advice.
