Customer Question

I have a evinrude 1973 85hp. Model number 85393. I have no spark on all cylinders. My question is on the terminal block. I have batt. Positive at terminal 8 and no power at terminal 5 or 6. Does the rectifier supply power to terminal 5 or should terminal 6 have battery power

Hello. My name is Tan.

That is not how you check for spark on this engine. Disconnect the black/yellow wire from the power pack. Now check for spark. Do you have spark?

The charging system has nothing to do with the ignition system.
