Circuit Breaker Question

The good news....got the boat in the water after engine rebuild! Ran great for 2 minutes on a sea trial....now back to the driveway to fix all the issues I found during the test.

It is a 91 Bayliner capri bowrider, 4.3 Merc, alpah 1

Having a strange problem and not sure how to diagnose and was looking for some help. Intermittently I go to fire up the engine and all I get is a click sound. The sound is coming from the 50amp circuit breaker not the solenoid. I tried the obvious, jumping across the solenoid and go nothing. There seems to be no power to it. Is it possible that the circuit breaker is toast?

When this problem occurs I can leave it for 5 minutes, come back and it fires up fine, other times it takes longer (hours).

There is no specific situation that makes this happen, sometimes it occurs when the engine has been run, other times I try and cold start it with the earmuffs sitting in the driveway and it still happens.

Hoping this is an easy fix....please help!

Re: Circuit Breaker Question

All you need is a voltage tester. See if there is any voltage getting past the circuit breaker. If there is no voltage and it wilnot reset then replace the breaker.

Re: Circuit Breaker Question

Thanks Boat1010

I will do that. Will I need someone turning the ignition to test this or should there be power always going to the breaker?

And again it is intermittent so it may read correct now and fail when I am on the water. Any additional suggestions. It's a cheap enough part so I might just replace the breaker and solenoid and take those out of the equation.
