Take white wire off CDI, if u have a test light put it on there and crank engine over, the light should flicker.

That'll do it if it has a metal point on the end

Did get a light...and when I was testing she cranked...for a second

When you say cranked, do you mean it sputtered like it was trying to fire up? With that white wire off the cdi, you should not be getting a signal to spark through the coil. In other words it will not send spark to the spark plugs. Was the light flashing while you turn it over?

Light came on...she only caught for a brief second. Can't duplicate it again...tried. now no light on tester

want to make sure i done it correctly. My tester has an alligator clip on one end and point on driver end. I removed the white wire, clipped the alligator clip to it and held driver point to cdi terminal while cranking.

Your trying to see if you have any pulsed voltage comming out of the cdi.
So you could connect the clip to ground and the probe tip to the wire comming out of the cdi.
Crank it and see if the light flashes.

If that works and you see the light flashing while you crank, connect that wire back up and do the same thing in the back box. Pull the white wire off of the coil and put the probe in there.
It should still work.
Then try connecting the clip to your black wire on the coil and probe the white one.
If that works. Check the resistance of the coils primary and secondary resistance.

Check all your fuses.

All fuses good...front and back

Only two fuses to check but if one of them was corroded a bit maybe the mpem isn't getting enough juice to fire but is getting just enough to engage the starter.

I get no light off black or white wires of rear ignition coil

How to check resistance. ..what setting on meter?

Unhook the regulator/rectifier, and take that out of the equation.

 

[fokker]

Where is the r/r?

RR = regulator rectifyer. Little box in the front electrical box that has the 3 yellow wires going to it. Unplug that. ( all wires to it)
It can interfere with the mpem sometimes.


Fir checking primary resistance. Set meter to lowest scale.
Connect to the coil where the black and white wires connect to.

For the secondary resistance (across the plug wires)
Set the meter to k ohms. It should be 8 ro 15 k ohms or 8-15 thousand ohms.
That check will just tell you that the coil is good or bad.

Primary...3.9-4.1

Secondary. ..6.7-7.1

Was it determined that there was a proper signal going to the coil from the white wire?

 

[fokker]

Never got a light

Unplug the R/R and see if you get a light. I just put the alligator clip on the neg of the battery and stick the probe in the end connector of the white wire.

 

[fokker]

No light

You are testing with the light while cranking the engine with the starter? Sorry, just dbl checking.

 

[fokker]

Yes
