Ignition Coil Resistance Check
- Connect ohmmeter between ignition coil primary and coil frame. Reading should be infinite on high scale of meter.
- Disconnect ohmmeter from coil frame and connect it to the other coil primary terminal. Reading should be very low or zero on low scale of meter.
- Disconnect ohmmeter lead from one of coil primary terminals and connect it to coil secondary terminal. Reading should not be infinite on high scale of meter.
