No Accessary power

[cyberlock]

Pulled boat out of storage and both engines started great but nothing else on boat has power. No horn, blower, radio, lights.
Single battery is fully charged. All cables are on and tight. 4 negative and 2 positive. I removed them multiple times. Is there a fuse or bank of auxiliary fuses? Circuit breakers are not tripped.
Thanks guys.

Yes...there is a fuse on the house + connection in a small black fuse container not far from the battery.

shouldn't you have 4 negatives and 4 positives,

As Julian said on the stock set up there's a small inline fuse in the under seat area where the battery is,

Yes Scott, I only have 4 negative and 2 pos. to battery. I removed battery and looked well. I found the inline fuse you mentioned but need to by one to check (20 amp?) Surprised blower does not work as I thought it was on its own line. If fuse to battery is bad would engines run?

 

[Scottintexas]

I believe it is a 20amp fuse. I checked my manual and couldn't confirm it though.

That fuse is only for the accessory line so the engines would run.

Can you see where your helm or accessory wires are spliced into one of those power cables? Follow that wire from the fuse location back and forth as far as you can.

Do you have any non-stock electronics on your boat?

No other electronics. I'll replace the fuse and see. Thank you.

I installed a new fuse block so this is all still fresh in my mind. I assume it's the same as my 210. The accessory fuse is a 20 amp. It's in a waterproof holder screwed to the side wall not far from the battery. You should be able to trace the smaller gauge cable right to it from the battery.

But something isn't adding up here. I thought I had 2 thick positive and and 2 thick negative cables (I assume for the starters/one to each engine) and then I had a single positive for the accessories, and a single negative with a bunch of small wires all tied together at the end where it connects to the battery - making for 3 total connections to positive, 3 total to negative. Are you sure you didn't mistake that accessory wire as a negative cable due to the black loom it is wrapped with?

 

[Scottintexas]

now that Vonce mentions it, I had a very troublesome radio, it's a long story but the guys that added the extra cabling used a red wire for the "ground" also, so I was trying to hook up all the red wires to the terminal not realizing one of them was actually the ground.

Did you trace that wire from the inline fuse? where did it go?

 

[cyberlock]

Thanks Vonce, I did hook up the accessory wire to negative due to the black loom. Everything works great now. I also replaced the 20amp fuse
since I was there.
