Thanks for the Info and to answer your questions. The kill switch, side stand, clutch and neutral switch all keep you from cranking it over. it cranks good just no spark on any cyilnder, no I did'n check for power on the coil but I will before I order the TCI. It did run al little rough when I first got it I but I put down to setting idle for 3 years and just needed run out for a fwe miles. I caled the local dealer and the quoted price for the TCI was about $880 i checked the internet and the price runs about $750 I don't want to buy one until I am convinced that it is bad. I need to try everything elas first. As for the wires from what I see on the prints the Black/ White stripe wire runs to the switched to kill the ignitor. Before the new electronic stuff they used to ground the coil to kill a magneto controlled engine. I was realy hoping to be riding this week end but i will just have to wait until I get it on the road. the only good thing if you can call it that is that it happened in the shop instead on on the road a 100 miles from home.
I can't see any relation between changing the oil and filters and the TCI failure but though i would rase the question and see if I may have mised something or if anybody else has that happen. It must have just been time for the TCI to go 25 years is long enough.
As to where I am in Pa. Mount Joy, Lancaster county
