So I managed to repair my TCI module last week. I built a test jig over the winter to run the module on the bench. Originally I thought the IC was kaput, but turns out it was another component,... that and replacing all of the electrolytic capacitors seems to have fixed it. Fault was D5 (12-03 module). Initially, the diode checked OK with the meter but that was only a cursory check since it is parallel with a cap. Could not get the test jig working quite right to simulate an operating module but the jig worked well enough isolate the fault(s).
Something about the timing of the pickup pulses in relation to the spark pulse... haven't quite figured out yet. However my basic understanding of how these modules work is correct. Just finished removing the pamco junk off the bike this morning, reattached the TCI and fired it up. Anyone need a pamco setup? Anyone need a TCI module repaired?
Have to sit down and order in a few other parts for the bike now. Looks like one of the camshaft seals is weeping. Hoping to be riding soon.
