Johnson J50TLERE (94 50 hp). Intermittent total ignition failure. Today I finally got back to troubleshooting the engine now having a DVA Adapter and using the CDI troubleshooting information.
The Stator Checks perfectly as does the trigger and charge coil. Since the stator checked correctly I followed the process outlined and removed the Regulator-rectifier from the circuit (yellow and yellow-grey wires). Spark to both cylinders restored. Hooked it back up and it still worked. (This has happened before during previous troubleshooting but I didn't realize it was because of the regulator-rectifier being removed and replaced.)
The first question is WHY did that work? I was told by some learned soul that the regulator-rectifier was not part of the ignition system and couldn't cause this problem. I have recently replaced the original regulator-rectifier with a used part because in the charge back circuit there was a 900 ma short to ground which was draining the battery. After replacement the drain was eliminated and is not back at this time. Of course it's possible that there may be two bad regulator-rectifiers.
I just don't see how this can logically be causing ignition failure. If it's not really the rectifier I would waste my money replacing it.
HELP!
