Fish finder amp Overload due to 2 stroke motors.-gctid384895

All two stroke boat motors with a generator/alternator built into the stator have a voltage regulator. It may not be working, but it had one at one time. It will regulate the output voltage to approx 14.2 volts to charge the battery. If it's not working, have it investigated.

Hello,

I was trying to figure out why my fish finder would keep shutting off. What i found out was that 2 stroke motors don't regulate amperage, so it fluxatesw. When I picked up speed it would shut off, probably due to overloading.

Has anyone else hit this issue? How did they work around it?

Thanks,

There's more going on here. Just because an outboard is a 2-stroke doesn't mean it lacks voltage regulation. Also, most fish finders are happy between 10V and 17V, or thereabouts. I suspect you have a bad connection on the power supply cable.

What make/model engine?

What make/model fish finder?

What is your charging voltage when idling, at 2000rpm and 5000rpm?

Have you checked for bad connections?

Don't worry about current (amps) yet.
