Any other tests you will need a Peak Voltage Adapter to test with your meter. Voltage at the Ign. coil should be100 VDC & 0.7 VDC at pulse coil

Try this -- put meter on AC scale -  place red meter lead under BL/Y connector on the ign. coil  make sure BL/Y wire is on coil -- black lead on neg of battery -- crank motor see if you get ac volts

6.5 volts on all three yellows.

 

That is AC volts?

Charge the battery up

You tested from y to y?

Test stator -- unplug the rectifier connector -- put your meter on the AC scale  check between the yellow wires for ac volts when cranking

The stator you put in did have the pulse coil with it -- if so check the 2 wire on the connector and make sure they are in the same place as the old one -- I found some stators were backwards

Try this unplug the CDI connector and remove the green wire from the ign. coil -- check for continuity on the G/W wire on the CDI connector to ground should read zero

CDI connector have 5 wire or 6 wires?

Neutral light is on when cranking?

Have you tried CDI that came with the ATV again?

That test where i hooked a wire to the ign coil and touched the battery directly. What does that tell us?  No spark at the grounded spark plug??

Some Ign. coils can be tested that way some not.

Does the ATV turn over real good when starting?

hate to break it to you ?, but you can not '' twist '' the kill switch wires together !!!. that is closing the circuit. when the kill switch is '' centered '' ?, these wires are not together, circuit open. when you move the switch right or left ?, you are closing the circuit, when this takes place, you are grounding the c.d.i., the spark plug coil, which then kills any spark to spark plug.

Kill switch needs to be closed --see dia.

I am signing out -- will keep thinking this over

Oil coil reads 8.6 with cap on

Reads 4.3 with cap off.

ok

Ok try this with the coil -- put the spark plug in the boot and ground the spark plug threads to the engine real good -- leave the G wire on the coil -- remove the BL/Y wire from the coil -- now place a wire on the tab of the coil that the BL/Y was on -- other end of wire just tap it on and off on the positive post of the battery see if the spark plug sparks --- 

Ign coil test

Did you do all the tests above? BL/W -- G/W --12vdc

HI It's 8:17 pm here now--- try this with CDI unplugged 

Ok -- do you have a service manual?

anything on the frame

Ok -- I will see what I can find and get back to you

Ok -- are you sure the ATV is 87 -- are there any tags on the atv saying what it is? I will see if I can find a print with 5 wires on the cdi with the wire colors you gave me

Does your atv have a fuel meter on it?
