83 Magna 1100 electrical question
« on: March 17, 2011, 01:00:31 PM »
Hi all in addition to my cb750's I also have a 83 Magna that I just started work on. It doesn't run, 2 cylinders have no spark, two have a very weak spark. I swapped out the coils for a similar set of Sabre coils, no improvement, could anybody tell me the ohm testing procedure for checking out the igniter boxes? And what is the procedure for testing the coils?

Thanks

Hows your battery? These things don't like weak batteries. Swap the ignition boxes and see if the bad spark follows.
