Jet Mate Electrical Question

[Jet Mate]

I have a 1990 JB650TS A-2 (Jet Mate) No Spark. I'm trying to trouble shoot - I have .2 volts from igition to CDI (white wire) when key is turned on. I think I should have 12 volts but cann't find any info in service manual. Seems to me that to charge the capacitor in the CDI I should have full voltage from igintion to CDI.

Would appreciate any help!

That system is an A.C. CDI, which means that the CDI gets it's "charge" from the stator, not the battery. How, exactly, are you testing for spark?

Pulled plugs from engine, holding plug against head. Have tried several plugs to ensure not a plug problem. Have used ohm meter to check resistance per manual on CDI and Stator Coil.

The Jet-Mate has some unusual electrics. The stator isn’t like most of Kawasaki’s ignitions, it has a much higher charge coil and the exciter/pulse coils are set up different. What usually happens on the Jet-Mate, are the safety lanyard and the ignition switch get water into them, reason being is they are set low in the boat. Easiest thing to do is first off make sure no water got into the electrical box, and in the flywheel area, this engine sit in a pan. Next disconnect the wire leading to the lockout (kill) switches and the ignition switch. This is the white wire and there is also a black wire, turn it over and check for spark, if you were to get spark it’s probably one of the switches I mentioned earlier. If you still don’t have spark after removing your switches you’ll need to start diagnosing the stator. Remember if you have any water in any of those areas that I mentioned you’ll need to deal with that, the stators have a low tolerance to water. I don’t remember a lot of Igniter failures with that model.
