Honda EU1000 coil test

I have an EU1000 coil "out of generator" that I would like to test.

The coil has three leads, Actual spark plug wire, ground wire and main lead wire. The ground wire connects to one of the mounting screws and the "main lead" runs off to the panel.

Need steps taken to check the coil with an Ohm meter. Service manual shows installed tests.

Thanks

  • mchero,
    I don't have a Honda manual, but a ballpark figure would be less than one ohm from ground to the panel wire & 7500 from the spark plug wire to ground wire & infinity from the frame to any wire.It could still have a minor internal short that would keep it from working. Most shops have a coil tester that will give a more positive answer.
  • Ohm from the spark plug lead to each connection and then from one connection to the other. If you have a reading all three ways, then it probably isn't the coil. I can't give you exact resistance that they should be.
