Super Jet Bad Rectifier? How to diagnose?

[Pablo]

What are signs/symptoms of a faulty rectifier? I've gone through my electrics from top to bottom with a volt meter and everything checks out minus the numbers for the rectifier. They're off a bit from the manual specs but it worked fine when I parked it this January after Daytona. I put in a new ATP Epic this winter (sold my last one). I've installed two now and it's wired up like the manual states. When I have it all buttoned up there's no signal or anything when the start button is pressed. No clicks, no buzz, nothing. I'm at a loss. With the relay powered up directly (not jumping the relay, but powering it) the ski turns over like normal. With everything checking out I'm assuming it's the rectifier. Any ideas?

Items ruled out:

Battery - fresh and topped off
Start/Stop Switch- meets all Ohm tests
Stator - Pulser coil WNL, Charge coil WNL, Lighting Coil 1.6 - 1.7 Ohms (specs = 1.2-1.3 Ohms)
CDI/Epic - checks out and brand new, wiring triple checked
Relay - turns the engine over fine when powered up directly through brown/black
Coil - 1 year old JSS coil and meets specs per volt meter
Starter - good to go...turns over engine fine with relay jumped or powered
Connections - all fresh and fully lubed with dielectric grease

I think you may be over complicating this a little if its just that the engine won't crank. Disconnect the start cable connector outside the e box, this is the one that has a red and brown wire going to it. With your meter set to ohms put one probe on the brown and one on the red and press the start button to check if its working. As long as the red is live and the brown goes live when you press the button the engine will crank. Just re read and see you have metered out the start switch so make sure the brown where it connects to the solenoid is actually going live when you press the button. The cranking problem is nothing to do with coils or Epic.

Chris,
I was overcomplicating it a bit, but I was at a complete loss. The rectifier was the only thing that didn't check out. The S/S switch checks out and the relay does too. The batt was fresh, the brain new, stator fresh as can be, the starter motor was fine, and the wiring was spot on...I thought.


I had the red wire coming off the rectifier to the fuse, but the other fuse lead was going to the starter side of the relay and not the battery side of the relay. As soon as I made the switch it fired like it was supposed to. Thanks for the input though. I had just been staring at it too long. I had gone over the entire setup two nights ago for approx 3 hours and couldn't find the problem and then had started back on it the next day for 2 more hours and it turned out to be something that I had just assumed I had done correctly from the beginning. I'm usually good at catching the small details, but this one eluded me. My riding bud Waternut helped me re-investigate the wiring and it payed off.

Man am i glad i found this thread...after blowing fuse after fuse...im gona go try this cause ive been scratching my head for months on why superjet hasnt fired up yet....
