Do you have the ohms readings for this coil? I bought one a few years back,I'm trying to determine if it has went bad.?
Sierra confirms that primary is 1.25-1.38 and secondary is 9,000-12,000.

Will this work on a 1984 omc 5.7 stringer drive?
We will need to know engine model number to match up correct parts for your motor.
