    need help with 1994 SL 750

    Hope someone can help...

    Have a 1994 SL 750. No spark, nothing, checked all cylinders, nothing...

    performed the following checks

    Excitor coil- 506 ohms
    Pulsar coil- 91 ohms
    Trigger coil- 216 ohms

    Ignition coil primary- all .4 ohms
    Ignition coil secondary- all 3.3 ohms

    the kill switch was OK...

    So, is it the CDI? Or something I may be overlooking....

    Help !!

    Has this engine ever worked properly for you?

    What is the battery voltage while cranking?

    I am the original owner, have not had any real trouble's since new. Ran fine last year, just pulled out of storage and you know the rest...

    I placed the battery on charger last night, so it would be under a fresh charge. The volts dropped to 10.1 when we first hit the starter, then up to 10.6, 10.7....

    I also trimmed back 1/4 inch on the plug boots, so have fresh wire. Again, all checks on coils, etc, show good?

    So, do you think might be battery?

    Battery seems to be marginal at best. Polaris PWC like a strong battery.

    You may have another issue, but a weak battery just makes the diagnostics difficult.

    OK, hooked the John Deere battery to the ski... Still no spark.... pulled the wires for the kill switch... still no spark...

    Help, any other ideas...
