Is anyone able to follow up on this thread with detailed instructions on testing the ignition control module that is used on these early '70s cars with points ignition? Are there ohm readings that can be taken on the unit to determine its condition?
Or, maybe someone knows if there are printed or online instructions available?
The MBZ CD manual has nothing about the ICM.
Neither does the big blue book.
Also, what is the method for changing the ignition wiring to bypass the ignition control unit? Which wires go where? Colors? Ballast or no ballast, etc?
Thanks!
