    Weird behavior after engine start

    I determined the cause of the melted harness to be some bad wiring from the previous owner. Caused a short and essentially ruined the harness. Once that happened I replaced the harness with a brand new one. I also inspected all the wires/connection that connect to the harness. I ended up...

    Weird behavior after engine start

    It didn't do it when I got it. However, when I got it. The harness caught on fire. Since then I've checked and/or replaced damn near everything on this bike. Is there something that would kick on or off at a certain voltage? Seems that the issue only shows up under the 11.3V range. Though this...

    Weird behavior after engine start

    While trying to follow this guide: http://xs650temp.proboards.com/thread/3461 Step one checked out ok. But I moved on to step 2 which seemed to exacerbate the issue (or so I thought). I noticed without the safety relay and lights jumpered on the 'dying' issue happens even with the engine off...

    Weird behavior after engine start

    Forgot to mention the hot ground wire is no longer an issue after re-wiring everything and re-cleaning/sanding grounding points. In fact I've checked all ground wires for heat and they all feel ok. Looks like this is the path I'll head down next. Maybe there is something going on when the...

Replace starter coil, ignition coil & wires, new halogen headlight, removed reserve lighting box (jumped wires), completely tore down all electrical wires and re-wired everything back together testing with required parts and pieces. Still have...

    Weird behavior after engine start

    Thanks everyone for your help! Given the latest developments I think I'm going to basically start from scratch. Remove all the wiring and ensure it's all up to par. Tired of tinkering around with no success here. Again, thank you everyone for your suggestions! I'll update the thread when I...

    Weird behavior after engine start

    Checked the ohms on the coils and they are reporting the correct values. I think I have the stock charging system. Is there an easy way to check? I tried tracing wires all over on the bike and could not locate the safety relay. Unless it's inline on the harness. Where should it be...

    Weird behavior after engine start

    I've been able to find the answer to most of my questions here. However, this one has me stumped: 81 XS650S As you can see, bike is starting fine. Runs for a bit then shuts off. I'm not touching anything after the bike starts. Then after a bit it comes back to life and I can start again...
