Reply To: Johnson FD-12 Won’t Run

[Bob Wight]

I wish I had a Merc O Tronic but I can only use my VOM to test the coil resistance.    The old coils measured 0.4 on the primary and 6300 on the secondary so theoretically they should be OK.    I’ve never had an ignition related problem after a total rebuild but then again, this is my first rebuild where I re-used the old coils.    I’ll just put in new coils and see what happens.  In the overall scheme of the cost of this project, a pair of new coils is nothing.
