Hi folks,
First time posting and need some help. I have been learning and troubleshooting my issue for a week and narrowed the problem down. Boat was running fine a couple of weeks back, ran for a couple of hours one day, then off to fishing and cut the engine off and then the dread of no-crank no-start when trying to start it up. So at key on we have no console/gagues, no click, no start. All of the accessories work fine (bilge, blower, lights, etc), but just not able to start the boat.
Jump to today and boat is out of water. Battery is good, connection to the starter is good, starter relay will click when 12v applied to signal input, also with 12v applied to the starter relay output (the wire that signals the starter solenoid) boat will attempt to crank so things look good there.
I have checked all fuses and none are blown that I can find and there is a 20a at the circuit breaker which has been pressed and no change. From all of the above I have it down to missing 12v on the starter relay input and the same at the key ignition red wire. I believe these should always have 12v and they do not.
I can not find a find a fuse from the key ignition back other than the circuit breaker and there the fuse is fine and we have continutiry through the breaker. I can not tell how power is provided to the key ignition and the starter relay input, does it back flow from the starter or should there be a direct connection from the battery??
Additionally, I can apply 12v to the key ignition wires, yellow/red and we hear the starter relay click and I can do the same to the purple wire and the gauges will light up.
