I have a 1980 xs650 project that I received about half completed. I wanted to verify spark before I continue to build. The bike has not run in over 3 years. I have videos of it running from the seller. It has the tcbros 6 pin harness and i am mocking up a very simplified harness for testing purposes only (i have numerous schematics of simplified wiring) , i am not using an ignition or running any auxiliary lighting, all stock components, again i am just verifying ignition systems. I am using a battery with ~12.6 volts. NO spark has lead me to read countless threads for days on troubleshooting the infamous tci box and wiring, all of your threads are very helpful how ever I cannot seem to solve my dilemma. I am getting sufficient voltage to the plug coil (proves path through tci?), in fact at times it got warm, it is evident i am not getting the intermittent ground or signal (orange wire) from the tci to primary coil. I have ohmed out (to specs from other threads) my pick up coil, primary coils to lugs and leads, plugs, verified resistance change while passing a magnet over tci pick up coil, verified tci pick up magnet with a nail WITHOUT power to stator, i have checked all my grounds from connections to battery and frame (~ half ohm on lowest setting) I have checked for continuity to ground with all coils and hot wires found NOTHING. I have unlanded individuals wires and ohmed to verify low path resistance and no breakage. I got spark with the reg/rec UNPLUGGED when the tci was initially powered up at REST, I then cranked the bike over with reg/rec UNPLUGGED and got no spark, ONLY spark at initial power up. When the reg/rec is plugged in the stator is powered up and the tci pick up magnet becomes weak and the nail does not stick to it well at all (favors the stator face) . Could i possibly have a weak tci pick up magnet on stator or is my rec/reg bad, sending power to the stator above the 12.5v setting and causing magnetic interference??
Any further troubleshooting steps would be greatly appreciated....
