My '82SJ (see pic) with original TCI system died suddenly on the road two days ago - I suspected the TCI might be bad and after getting the bike back home, tested the TCI by hooking up a tach and dwell meter to the orange wire that drives the coil. I've used the same meter and connection in the past and have gotten reliable rpm readings with the engine running. I can't think of any reason why the meter wouldn't respond when the engine is turning on the starter motor, as long as a signal is appearing and disappearing on the orange wire as needed to drive the coil. Removed both spark plugs (and grounded them to the frame) so I could get enough cranking rpm to move the needle off zero if the TCI was working, but the needle never budged off zero. Does this sound like a valid way to determine if a TCI is good or not?
