Hi all:

As the refitting of hull 922 is proceeding nicely its time to tackle its electrical issues...

Switching on the various stock circuits does not cause that circuit to work - cabin lights, bow, stern, steaming, and anchor... the three accessory circuits do power-up the devices on those circuits - VHF, stereo, and Raymarine depth/speed...

So, before I go heavy into diagnostics - is there some hidden fuse or secret switch that I need to look for to make the fundamental circuits operational?

Thoughts appreciated...

Carl

I had a similar problem, I pushed that black reset button on the panel and everything worked again.

Thanks Steve. Pushed the reset buttons onbothe circuits... accessories still work and lighting circuits still don't work.

Going to start looking for a bad ground connection next.

Take a test light to that upper fuse. If you have power before the fuse but no power after the fuse then the fuse is your problem and needs to be replaced. The upper fuse feeds and protects the circuits that aren't working.

Yes - crossing the poles on the back of the breaker shows power through the test light...

Then things get weird crossing the switches... some illuminate when switched on while others don't...

???

More to follow...

Carl, I'm not sure what you mean by crossing the poles.

using the test light with the clip on one terminal and the needle on the other terminal...

I'm at home this afternoon but will be back on board on Wednesday to take a few pictures of the testing process.

Ok, What you want want to do is put the clip on a ground wire then touch the point to one side of the breaker then the other side of the breaker. If the breaker is good your test light will light up on both. If it only lights on one terminal and not the other and the breaker button is pushed in then the breaker is kaput.

Thanks Islander and Tradewinds.

With your help I focused on that breaker... and that was the problem.

$10 and a quick trip to West Marine resolved it.

In the pic I`m jumping across the bad breaker and the cabin light works.

As I felt I had more pressing tasks to attend to - this was the first time I had seen any light work on the boat in the three months I`ve owned it - crazy.

Good deal! What made me focus on the breaker was that you had power to the panel but no power to the upper part so power wasn't getting past the upper breaker. Bills in the mail![:D. I've always had good results with breakers and switches if you lube them with WD-40. It keeps them working smoothly and helps with corrosion. I give them a squirt at the beginning of the season.
