ahhhh i have a feeling we only checked it on DC , will look at the meter tomorrow...


If it is showing something with the meter set correctly , what else could it be lol

Here is a tutorial of no spark: To get spark here is the flow"
1. Plug
2. BOOT CAP
3. COIL
4. CDI
5. Stator
6. Pick up Coil

So naturally you would make sure the stator is feeding the CDI and the PICK UP COIL is sending the signal. If those two are good then its either the CDI, COIL, BOOT CAP or PLUG or bad ground.

Also make sure the killswitch is on the run position and or disconnect the KILLWIRE from the CDI- to Eliminate that possibility.
Also Ground wire from the Frame to the MOTOR.

Coil , lead and cap are new, cdi new, plus the old cdi, 2 spark plugs and its getting a feed from the trigger from the pick up coil,we did the kill switch test and tried it disconnected too , not really much left is there, so if it works on the AC setting on the multi meter ?? ??

check the crimps on the connectors and that the connectors are tight . Ignition power coils from the stators are stable , either good all the time or bad all the time . I keep a dc cdi for testing that kind of problem .

Here is an example of a poor crimped connection scooterdoc.proboards.com/post/74056

All is well

Had another look at it today, we found a wire to the stator that had previously been messed with (prior to me owning it) had come loose and the CDI unit was picking and choosing when it worked...so reconnected the wire , put on the new CDI and Bingo!! Running brilliant

Thanks for your help x
