Is it common for the trigger in the timing base to go out on a 99 Johnson 225 looper?? I’ve tested with multimeter and I have no power coming out. Pulled the flywheel all magnets to include center magnet is good. I have no spark and have tested everything and the only not reading is the timer base. I’d hate to sped $300 and it not be my problem. Also do any of you all know of a boat motor junk yard where I might be able to get a used one to try it before I spend that much on a part that’s non returnable? Thanks for any help!!
