DO YOU HAVE VOLTAGE AT THE COIL..POSITIVE SIDE WITH THE KEY IN THE "ON" POSITION?.....DISREGARD MY READINGS IN THE PICS

A CHEAP VOLTMETER IS FINE...."HARBOR FREIGHT" HAS 'EM FOR ABOUT $5..........WE CAN USE IT FOR FURTHER TESTING

DO YOU KNOW HOW TO USE ONE?.....I CAN HELP WITH THAT TOO!

I'M MORE OF A CJ GUY......MY PICS ARE MOSTLY CJ

...........CAN YOU TRANSLATE MY INFO TO YOUR NEWER MODEL?

I ALSO WANT YOU TO REMOVE THE DISTRIBUTOR CAP AND VERIFY THE ROTOR BUTTON TURNS WHEN YOU TURN THE ENGINE OVER WITH THE KEY (HAVE YOUR BUDDY WATCH)

STAY ON THIS THREAD!

I HAVE MORE STUFF

I'LL DO MY BEST-US!
