Motorcycle Repair: Honda cb 500, honda cb 500, coil windings

Question
I have a 1976 Honda cb 500 that isnt running.  Ive been advised to check and clean the carbs.  That has been done and as I was checking the elecrical componets, I noticed that with the key on one of the ignition coils became really hot while the other remained the same temperature. I turned the engine over to see if the problem would move to the other coil and it does not. Is one of my coils or points bad?

Answer
Hi Matt,

Sounds as if the ignition coil windings is defective.

Measure the resistance of the primary and secondary windings with a multimeter.

Compare specs with those of the service manual. If you need service manual information, advise.

I return test and repair information files via email. There was no email address with your question as requested.
