  • Trigger coil resistance testing

    I have been having idling problems now it has a very bad miss, at all ranges. I am suspecting the trigger coil.Does anyone have the resistance readings for a 1984 90 HP, I have a Clymer manual but the chart was never put in the manual, does 20 to 32 ohms sound about right.
