explain in detail how you jump started the boat, there may be a clue there

 

[mazzen66]

Remote starter switch, poss on starter and the ignition tab on the starter. I bench tested it first.

 

[dennis461]

do you have a relay somewhere on the boat in addition to the solenoid?
Or is it the simple system shown below which makes the ignition switch fail?

battery + --------------key switch------------neutral switch----------------solenoid terminal

battery - --------------------------------------------------------------------------solenoid metal frame

 

[mazzen66]

Yes ,a relay by the starter ,it hooks to a ground on the engine and to the 40 amp circuit on the engine and also to the dist coil and to the starter's ignition. I have changed it out but dont have the original one in it .just bought one at napa and it worked .

 

[mazzen66]

I also have jump past the neutral switch in the controls and both end get power.

 

[dennis461]

could be your boat is miswired.
Does the solenoid have four connectors or three?

4 . 1 power 1 power to motor 1 for starter wire 1 open. I'll send photo.again Thank you for your time.

No Title

Here's some shots . I've unwrapped the wires.

 

[dennis461]

No Title

I would get to the wire on either side of the ignition switch/neutral switch combination and jump those.
Your solenoid and starter are good from your previous test (good news since that's the most expensive repair).
Put your small wire jumper on the ignition switch positive, jumper to other side of neutral switch.
JUST MOMENTARILY

I'll bet the ignition switch is old.

 

[mazzen66]

I have already tried the jump past the neutral switch,and installed a new ignition and still nothing.

 

[mazzen66]

That's what makes it confusing.

 

[mazzen66]

I will see if the relay is installed correctly, as per drawing. Thank you sir .

 

[mazzen66]

Thank you for the info it worked ,the relay was hooked up wrong.yahoooo! And still have some hair left.what a relief, well I fixed alot of stuff in the process.
