CDI on 96 XP

[Jparadise81]

Let me preface by saying, Im no electrical guru and Im working with a cheap harbor freight meter. With that being said, I took the CDI out of the ski and tested it according to the manual but was unable to replicate any of the suggested ohms readings. Does that mean this thing is trashed? Just asking becasue I have no clue what kind of readings a bad one would throw out.

BTW, Im diagnosing a no spark issue. I have a new mpem, new battery and checked the pickup coil this weekend and its still attached and there werent any shavings. Already replaced the ignition coil and clipped the plug wires and put in new plugs.

Thanks for the help, just trying to decide if I should go ahead and order one or not.

I had the same thing on a 96 xp. No spark. Turned out to be the Cdi. Put a new one in an it ran perfect. Hope this helps.

Yeah a HF usually will test within spec, I would say if it was close to spec it isnt it, but if its way off its prob bad.

They def do go bad, but the pickup in the mag housing is more common. Trouble is its not a real fun project if it doesnt turn out to be broken.

I have a CDI in stock if you need it.

How much for a CDI?

Thanks Minnetonka. I have a broader question for everyone. As I mentioned Im no electrical guru so I want to make sure Im testing this thing right. First, I removed the CDO completely from the ski for testing, is this right or does it need to be hooked up?

Next, according to my wiring diagram the white wire that sends a pulse to the ignition coil comes straight from the CDI without passing through any other modules or relays or anything. When I took off the CDI and ohm tested the white wire with the black, it shows 0 ohms. Does this mean it's grounded inside the CDI and therefore the CDI is no good? According to the manual it should read 2.2M ohms.

Now the funny part about this (which led me to replace the ignition coil already) is when I hook up an led light between the white wire and ground on the ignition coil I get flickering when I crank. I dont have a regular bulb style light tester and maybe the only reason I get the flickering is because it doesnt take much to light up an LED. One thing for sure, I have a spark checker and Im not getting spark.

Any help is appreciated as Im trying to avoid throing any more undeeded parts at this thing!

Throw up the wires/ohm specs you are lookin at and Ill go do a test.

 

[Jparadise81]

Here's what the manual says it should spec at.

 

[Minnetonka4me]

what values are you asking to be tested?

 

[Jparadise81]

Can you just verify that your CDI tests at the specs. In particular between the white and black

 

[Minnetonka4me]

Ok they do not test within spec at all...lol I tested two of them and not one value came up correct.

White+ black- 2.395mohm and 2.780
Black- White + Seems to climb to infinity then it stays there till I do another test.


Heres a list in the same order as the one above off one CDI

3.49
.567
2.395
infin
infin
.4
29.87
3.44
.569
infin??
2.567??
2.586??
0.00??
29.87

Lol. Guess ill just have to get one and see if it does the trick. I know it's not the regulator since I bypassed it. I tested the white wire and I'm only getting between 1 and 2 volts going to the coil. Does anyone know what the voltage should be??

Houston we have spark! New cdi did the trick...thanks Minnetonka.

Yeah buddy!!! well we all learned something. Screw CDI values.
