Electrical questions

Ok everyone i know this could one of a few problems but i figured i would explain my situation and see what i can get as far as suggestions. I have a WB1 760 recently my starter went out (solenoid clicked when start button was pressed and again when released) so my solenoid was clearly sending power but the started was not turning. I replaced the starter and gt everything back together. I pressed start and the engine fired and idled for a few seconds then stopped. I press the start button and i get nothing at all. no click, no nothing. i was thinking this might be the solenoid dying but that almost doesnt make since as the engine had already fired up and died. im questionable about the kill switch. What are your thoughts?
 
Remove your cables from the battery and check for corrosion between the surfaces. Had this happen on my superjet. Removed the cables and hit the contacts on the wires and battery with a wire brush and it worked like a champ.

We've had this same thing happen...
We replaced the starter on a SJ, it fired up and ran. As soon as we dropped it in the water,...Nothing, no click...nothing.
Ohm'd out SS switch and it was good.
Ohm'd out the ground from the battery to the engine and nothing.
Pulled the starter back off to find that the mount flange where the ground cable and upper starter bolt goes was painted over. The voltage/amperage jumped from the bolt touching the inside of the bolt flange.
To make a long story short... Sanded the paint off, Problem fixed!!!

update. with the continuity tester: solenoid is working. Starter is working. fuse is fine. battery is good. start switch is good. killswitch seems to not have a circuit but when jumped from the ebox still will not fire. i am going to spend my saturday testing every single wire in the hull. any other suggestion are welcome and if i do diagnose the problem i will post it.
 
ok guys i fixed the problem and im going to explain my process of elimination so that everyone that reads this will understand and hopefully find my method helpful.

First: i tested the battery and found it was working properly and that my fuse was also working (replaced fuse anyways for good measure).
Second: i used a continuity tester to check me large power wires from the battery to the solenoid, from the soleonid to the starter, and the ground from the starter back to the battery. I found all of which to be fine.
Third: i used the metal of a screw driver to touch the two large metal parts on the solenoid (this send electricity directly to the starter and will tell you if your start is working or not) (although this will spark violently so be prepared) This caused the starter to jump on in an attempt to start the motor. (this tells me that the Battery starter and wires between them are fine.
Fourth. I completely disconnected the solenoid. I put the power and ground (small wires used to power the solenoid itself) directly to the battery and heard it "CLICK" which means the solenoid is working. I then used the continuity tester on the larger posts on the solenoid while a friend applied the power to the solenoid. When the solenoid "clicked" we had a good flow of current on the solenoid.

so far: battery is good, wires up to thus are good, solenoid is working. This leaves the wiring the solenoid is then connected to.

Fifth: i reconnected the solenoid and began to use the continuity tester to test the wires tracing from the main power wire through the chain of power in the wires. ALL which were fine.
Sixth: i removed the plugs for the start stop assemble and with the continuity tester found that these were also in working order.
Seventh: after testing the flow of power which seemed to be fine, I disconected only the power wire on the solenoid and connected it directly to the battery. NOTHING.

This told me that it was not a power issue but a ground issue.

Eighth: i used the continuity tester to test the ground wires to the ground post and everything was fine.

COMMON KNOWLEDGE: everything in the Ebox is grounded to a double bolt post which is then channeled down a ground wire in the stator assembly and grounded to the case on the front of the motor.

so from here the only logical end to my problem is that the ground in the case was out or the wire in the assembly had burnt out.

I opened up my case and found that the screw holding the ground wire in the case had backed out and gotten thrown and ground my stator up.

Replaced the stator assembly... and everything fired up and idled beautifully. Problem solved.

Hope this helps guys!
