MSD enhancer pooped....one spark at end

What he said^. You can also try unhookING the stop wire to verify it is not the switch.

Thanks guys. Already tried unhooking the white and black stop start. And the msd is brand new from jet maniac. I guess next is to try stock cdi.

I really really realllllly hope I didn't just burn $300 on a new msd.

Or incorrect installation.

This does not mean the Enhancer is bad for sure. If you reverse two wires this happens. Can't remember if it's the white and the white/red or another two. @Little_Franny knows off the top of his head I believe. Seems to come up every few years, just long enough for me to forget which two wires.

I did the white/red wire correct following the instructions . I will look over it again tomorrow. Thanks

I second, (or third), the notion that the white wires are backwards.

You would think that MSD would have figured out a way to distinguish between the two white wires.

LOL, yea, 2 white wires out of msd and white and white/red in ski, easy to reverse, if reversed symptom is spark only when letting go of start button

A high cranking load will cause the same thing. If you have a spare starter swap them out.

I had a 650sx i sold 6 yrs ago that had the same problem, and I just bought it back last week and it had never been fixed. While cranking it the other day it the starter was noisy so i decided to put a new one I had on. I'll be damned if it didn't fire right up, and continues to do so. When I sold it the starter sounded fine, and cranked fine, but it was absolutely the problem.

Absolutely this, backfires that will make you pee your pants.

Or shear your woodruff key. Ask me how i know!!

If the msd is bad they have a 1 year warranty.

Mine did that when the pulser coil on my stator crapped the bed.

I finanaly got the ski running. It was a combination of 2 things. Actually 3 things if you also count me being a dumbass

We are all dumbasses at one point or another so the third point is moot and doesn't count.

 

[Raddog]

So what was the combo of things?

so the main problem was a bad start stop switch. when I unhooked the white and black wires on the switch the first time and it did nothing I ruled it out.
It did nothing because I only skimmed the msd instructions and didn't hook up the red wire in line with the fuse. I thought I read it was for the holeshot device and wasn't needed. I swapped to the stock cdi and still got no spark. (because start stop was hooked up) Then I double checked the flywheel key and timing and that was all good.
I finally unhooked the start stop again with the stock cdi and was getting spark. . tried the msd again but no spark . after a few more swaps I checked the msd instructions and saw the pink was for holeshot and the red needed voltage.

so now I guess the next step is to take apart the stop start and clean it??
or should I buy a new one???
or are there rebuild kits for them or anyone that refurbishes them??

thanks again everyone for the suggestions
