clueless??

[woodielvr]

so all the sudden when i turn the key i get nothing..no click..no nothing..?..so far i have replaced the solenoid,coil,ignition switch,and had the starter tested and still nothing.i have juice on the tester from the main bat switch all the way down to the starter and everything in-between..she is a 65 trojan 27 with a chrysler 225 LM318 model..am i missing something??

No ground strap?

Try taking a pair of jumper cables and ground black to engine block,then take red cable to big bolt on starter it should turn over. If not it is poss. a bad solenoid or a flat spot on the starter. I have seen brand new starters bad out of the box.

Try testing the voltage at the starter when someone hits the key. You can have voltage when at rest and not enough when you hit the key to activate the solenoid.

hmm,I have tryed the test with the cable going straight to the starter and it does turn..so that means its not the soleniod right?..the batteries are both new should have enough juice..but ill try that....
could the netural safty switch possibley cause this?

[skipmac]

If the starter (and engine) spin full speed when you connect the jumper to the starter (you did connect directly to the main positive terminal on the starter body itself, correct?) then the problem not the starter but could be the solenoid. To check the solednoid apply power to the positive terminal of the solenoid and see if it clicks and the starter spins.

If the starter/engine turned over normally when you jumped but the engine did not fire up or even sputter then it could be the neutral safety switch is involved. I am more familiar wth diesels so not so sure about this one but believe the switch basically kills the ignition system but could be any number of issues with the ignition system (another reason I like diesels).

Good luck.

Jumper Direct to the big starter lead and it turns - good starter motor.
Jumper dorectly to the solenoid connection - Click heard, starter spins - Good starter.

Neutral lockout - if installed
Panel power - if a panel is installed
Panel push button switch - if installed
panel key switch - if installed

Starter neutral interlocks are usually fail open. That is if the wire fails the engine won't start.

A wiring diagram for you boat would be useful but being so old it probably doesn't have one.

You might want to diagram it for yourself or trace the wires to see what equipment is installed.

A boat that old, I would check for corrosion on the wire terminals. If they're green or powdery or both, you're in for a fun time.

It maybe time for a re-wire job.

the wireing has seen better days thats for sure,been trying to avoid jumping into the re-wire but its pretty much coming down tom that..thanks everyone
