1986 Johnson 40hp short circuit

[bluefightingcat]

Today I was working on my Johnson outboard. I accidentally connected the cables to the batter the wrong way round. There was a small crackling noise coming from the engine followed by smoke. Once I removed the cowling the smoke was gone and I have no idea where it came from.

I then proceed to check everything and all seemed fine. The starter motor worked as soon as I turned the key and the engine would run.

I am just wondering whether something did actually break or whether it was just a scare.

rectifier could have fried...engine may run but won't charge anymore. it is not a regulator so a $10 3 phase full wave rectifier should do the job

Thanks. I'll have to check that out!

I have another engine. A 1998 Johnson 40hp. (BJ40TLECR). It's not charging the battery when running, so I suspect it's the rectifier or the stator. I am looking at the rectifier first. It seems that this model has a rectifier and regulator. Seems to cost a fortune. Is there an alternative?

Easy to test stator with flywheel in place.-----Find a used regulator on E-BAY ??
