Evinrude 130 Rectifier?
 

96' Evinrude 130 v-4

Went to take the boat out this past weekend and had no fire so I started troubleshooting using this guide. http://www.outboardignition.com/page30.asp "Four Cylinder Engines" at bottom of page.

I do not have spark on any cylinder until I remove the yellow wires from the rectifier. I then gain spark on the #1, #2 and #3 cylinders.

I plan on replacing the rectifier. My question is regarding the #4 cylinder with no spark. Could this be an issue related to the rectifier or another problem all together? With a faulty rectifier unhooked should I gain spark on all cylinders?

Thanks,
Curt

probably a coil issue, check the ground strap on the coil, or swap the coils with another cylinder, if the problem moves with the coil, you know its bad

Thanks,

That was my first assumption so I did as you said shortly after I posted yesterday. The coil checked out when moved to another cylinder so it was not getting signal to fire.

Unfortunately it seems my problem is intermittent and is going to require some more tracking down. Messing with it today, I now have spark only on the #1 and #2 cylinders with or without the yellow wires removed. I guess I will move on to the next step and check the stator.

My moneys on the power pack, I'd be willing to even wager money on it. You NEED a peak reading volt meter to properly diagnose an OMC ignition system, unfortunately theres no way around it. Check the resistance on teh stator to ground and make sure that is good, if it is I would be willing to wager money on a failed power pack.

go with what Ferm said. My Proline was only missing on two, I cleaned the coil grounding straps, got it to just one missing, tehn went back and checked the outputs, power pack was bad, after I replaced it, I found one of the otehr coils wasn't grouding corectly, ended up putting a new power pack on it, and four new coils

Thanks guys,

I will check the resistance tomorrow. The cheapest peak volt meter I found after a quick search was $290.00.

I think I will just buy the power pack if the resistance checks out.

If you have a basic volt meter that uses the standard bananna plugs, you can buy a PRV adapter from CDI for about $75. That's what I use.

The stator resistance checks out according to the guide. After some more research it does appear the power pack is going to be the most likely cause.

Thanks for the help guys, It will probably be a week or so before I order the power pack. I will update when I get it in and installed..

what i've always found was if you turn the motor over and work the timing advance for firing at the flywheel you will regain fire the stator's will need working to wake them up i would only fix the rectifier first it may come to life once you fix that, crank it the # 4 may come back to life with extra RPMs on the flywheel the starter can't spin it that fast. a new powerpack may not fix it may just hurt the pocket.

I have actually gotten it running a few times. I have reved it up to around 4k several times. The problem still is intermittent.

It seems the spark results differ day to day. All cylinders have fired a few times, only one cylinder sometimes and other times it's a mixed bag. I never know what cylinder will or will not fire. Today I am only getting spark on the #2 cylinder. All variables are the same during the tests. The coils on the dead cylinders have been swapped and the problem stays on the dead cylinder.
