Zapped the switch panel and stereo, can't find fuse!

Lake_Bum · March 2017

Okay so I pulled a rookie mistake today. I was testing the terminal on my switch for courtesy interior lights, and shorted something out that I touched with the test light. I heard a small zap, and it killed power to ALL my switches, for nav lights, bilge pump, blower, courtesy lights, and power to the stereo. Dumb dumb dumb......what is even dumber, is I cannot find the fuse! It didn't trip any of the little pop out breakers on the panel, and I crawled under the helm, and there are NO fuses. It didn't trip the big 50 amp on the motor, and I cannot for the life of me find the fuse that got zapped.
The reason I was messing with it, is I plan on adding a few LED lights to run off the same courtesy light switch, but I screwed up from the get go

What am I missing? Thanks!

There should be a fuse in the engine compartment that runs the helm. It is either by the battery or where the main wiring harness connects together. It will be a thick red wire in the harness that heads to the helm. It has been a few years since I have been in the engine compartment of a 232. I sold mine four years ago. Worst case, reach out to @Alswagg. He will be able to point you in the right direction.

Thank you. I looked and looked, and couldn't find one earlier. It's frustrating when you know its something simple haha

Lake_Bum · March 2017

I did find one fuse right by the battery, I didn't trace it back to where it came from, but it did look factory, as the wires went through the back wall, through a sort of plug. It wasn't blown. I will look more tomorrow

Lake_Bum · March 2017

@Cableguy Greg is it one of these?

Lake_Bum · March 2017

The fuse by the battery was okay, that is the same one with the wires threaded through the wall. The first pic is a fuse that is a PAIN to reach, down way low, behind the block. I'm not sure if it was blown, because I broke the dang thing trying to get it apart! My contortionist skills aren't up to par haha.

Lake_Bum · March 2017

Another view of the one I broke

Lake_Bum · March 2017

The one I broke goes to the Mercathode on top of the block. No clue if that fuse could be tied into the gauge panel...this is the first boat i have ever owned, that doesnt have a traditional fuse panel.

What kind of boat is this?

@Handymans342 it's a Captiva 232

Lake_Bum · March 2017

The fuse right by the battery, was from my factory VHF ship to shore radio, so that one is out of the loop...

Cableguy Greg · March 2017

One of those was for the Mercathode. It gets power directly from the battery. Did you find the main harness that goes from the engine room to the helm? It should be on the starboard side of the boat. Follow it back to the engine. There should be a large molex connector with about an 8 AWG red wire in it. Check for power there. You should be able to trace that wire from the connector back to the alternator or the battery. Somewhere there is a fuse.

Snow is coming tomorrow, so I'm sort of on hold now. Don't ever believe anyone who says it never snows in Arizona

STILL cannot find any blown fuses. This is pissing me off, I'm going to have to PAY a mechanic to troubleshoot something as simple as a fuse

on my 270 there is a fuse block behind the steering wheel. extremely hard to find and see. found it while installing switch for underwater light. I had the gauge cluster and the key switch panels out running wires and things and found it.

Lake_Bum · April 2017

I was in there, and didn't see a single fuse under the dash. It's like the fuse block is invisible! UGH

Cableguy Greg · April 2017

Did you ask @Alswagg if he has any tips? Send him a PM and see what advice he can give.

I just now did, thanks. I can't believe a stupid fuse has me stumped

Cableguy Greg · April 2017

If anyone on here would know, it's Al. He used to work at the factory.

You could very easily have a bad reset breaker that shows good visabally but did not pop out. Understand?

Yes. That could be a possibility as well. I somehow shorted the switch with a test light....it was a definite ZAP.

Handymans342 · April 2017

Any luck on this yet?

Lake_Bum · April 2017

No I never could find the source. My boat is in the shop getting a full spring tuneup, and he's looking at that as well. I'll report back soon

Lake_Bum · April 2017

Turns out, there was a fuse, tucked in down below the starter. My contortionist skills weren't up to par to see it apparently!

Handymans342 · April 2017

Wow

bella-vita · April 2017

At least it was only a fuse

Cableguy Greg · April 2017

Glad you found it.

Lake_Bum · April 2017

It definitely hurt my pride to hear it was that simple haha! He didn't charge me for it, but the list was long of other things. The boat is completely serviced, and ready to roll for the season now

Dream_Inn · April 2017

Well, you learned something today & that's good! & even better, your boat is ready to go!!

Howdy, Stranger!
