[QUOTE="CarlHungness, post: 173413, member: 2517"] If what you describe has happened, I have to wonder if it caused just enough damage to allow the unit to spark a plug in open air, but not under compression. The B-TH bench tests ok, will spark if I hold it against the clutch lever and kick, without the plugs in, but won't start the bike..and if it does, it just 'ain't ' runnin' right..and can't get it re-started. I KNOW the kill switch has not been disconnected in years..but last year I couldn't start the machine..finally did..rode it to my new shop..let it sit. And out of the blue I dis-connected the kill wire and began replacing the coils, new wires, bench tested the B-TH, etc..and when I did get it running I tried to re-connect the kill wire with its connector..and when touched the bike died! Can't be..the button was three feet away. Got it started again next day, and same thing..ran rough, tried to connect the kill switch, just for a test, and it killed it again (almost..I just touched the wires)..and kept running..so the button is bad..and wonder if the feedback it was giving last year muffed the insides of the B-TH. No visible damage, I took it off today and took covers off, and all looks un-scathed inside, no burns..tiny black wire is kill wire and can't see how to dis- connect...but am not using it anyway.
