Before I go through the ugly task of replacing the ignition switch in my 1988 930, I thought I would check to see if my logic makes sense.

Re-installed engine/tranny. complete with new wiring harness, alternator regulars. Previous harness melted (long story).

Went to re-start and the starter would engage but would keep running, even with the key pulled out! Had to disconnect battery.

Test:

Using heavy wire, jumped between terminals on solenoid (+ve from battery and yellow from ignition. Did NOT take yellow ignition wire off terminal post). Starter fired but ran continuously even with jumper pulled.

Removed yellow wire that comes from ignition switch to solenoid. Just jumped from battery +ve to the terminal where yellow was attached. Starter turned and would stop when jumper pulled. Could even start and run engine (JOY!!).

This says to me that once energized, the ignition switch "sticks" and causes the solenoid to drive the starter.

Conclusion: Replace the ignition key switch electronics.


Does anyone see anything wrong with this logic??

Thx.
