Hello all, I'm trying to help a friend whose bike won't run. Well, it DID, but now it don't.
Bike is an '82 (8/82 on the VIN sticker) that the PO has amended to get rid of the battery box. He welded a tray for the electrics into the frame, so not rubber mounted. The sidestand and headlight relays are gone as is (I think) the clutch relay though the cable from the switch at the lever disappears into the headlight shell - whether it's attached to anything downstream I couldn't say at the moment.
Symptoms are that the motor ran quite happily and then stopped, and now won't run. There are no sparks.
So far, plugs have been replaced, the trigger coils tested (well within range), the coil swapped with mine and so far to no avail. Motor is well earthed/grounded. Kill switch is OK and fuses are sound. Curiously, when keying off there is a spark.
I'm suspicious that the rigidly-mounted TCI unit has given up from vibration, so there's no signal to the coil. I'm not aware of any simple way to test the unit and I've about run out of other ideas. Can anyone offer some thoughts? Have I missed something?
Thanks -
Cliff
