Unhappy wave runner electrical problem

We have a 1988 wave runner and accidentally crossed battery polarity when jump starting. Now its dead. Any idea which electrical components need replacing or how to test them?

Hello: skipbros. Welcome to the Boats, Sailing, Pwc's & Navaigations topic and the Do-It-Yourself Web Site.

Unfortunately, reversing polarity can burn up more than one electrical componet or electrical part. Testing, finding and dretermining which (part(s) usually takes professional diagnostics equipment and an electrical professional.

Best bet would be to have the wave runner tested at a local dealers or repair shop that repairs this type of water vehicle. You could spend more money and lots of time and not resolve the problem. Many have been there and done that without much success.

The diy resident boat service & repair professionals will have additional helpful information, suggestions and advice. Check back on your question several times for additional replies.

Merc is correct. The fuse should be in the black electrical box. There is a thread-on cap that you'll need to remove, and inside is a black fuse holder in-line on a red wire - you'll need to pull that out. Yamaha often includes a spare fuse attached to the wire.
