    95 slt750 ignition question

    I am trying to track my source of no spark. I swapped out the cdi box and no luck. i took a multi meter to the ignition coils like the book says. the book calls for 0.6 ohms. I checked 6 of them and all of them go to 0.6 but then drop to .5 and come to a stop on .4 the longer I hold the leads on the wires. is this normal or do I have 6 bad coils. Doing the other test on the coils that the book calls for, one to the b/w wire and one to the spark plug wire, it calls for 3300 ohms and I get that
    any help would be appreciated

    next question,

    Checking the stop switch, the book says it should be less than .3 ohms. The meter stops on .3 does this mean its bad?

    Ok, think I may have screwed up 3 of my coils. is it ok for the plug wire to be removed from the coil. I pulled them off of my parts machine. checking resistance on those three I get the 3300 ohms. checking per the book (small black wire and the spark plug boot ) on the three on the machine, I get nothing. Im confused, Im a noob. (if you couldnt tell)

    What are the stator readings?

    I ran out of daylight. I talked to an electrician who explained ohms to me a bit.

    I hooked the 3 coils up to the plug wires of my parts machine and was getting secondary resistance readings of 8700 ohms. on the wires of my slt, I get nothing.

    he said it sounds like there is corrosion or something on the wires to the parts machine, and the wires on the slt are bad.

    does that sound right or do I need to keep investigating

    beerdart, i really appreciate your help, you have been the quickest and most often responding person when I post questions.

    Remove the plug boots and check again. The boots are resister type.

    did I ruin the 3 coils by removing them from the wires or would they be ok. what about the wires not reading any resistance at all.

    OK I did somemore testing.

    I pulled the boots off the plug wires and got readings of

    1- 3230
    2- 0
    3- 3230

    Exciter coil

    should read 490
    actually read 483

    Pulsor coil

    should read 90
    actually read 85.6

    Trigger coil

    should read 220
    actually read 214

    Incidently, when you remove the plug boots, should the metal connector stay in the boot? All 3 of mine did and I got my readings by sticking the lead into the wire.

    would that one ignition coil being bad prevent all three from getting spark?

    In case you dont remember, I got water in the engine compartment and sucked a little into the engine. I pulled the flywheel plug and it looked like it had water drops on the fly wheel I sprayed contact cleaner in there and hit it with air, still havent had spark since. The inside of the box was dry when I opened it.
