1996 Seadoo GTX 787 - No Spark, Please Help!

[2strokenewbie]

Hi All,

I am the new owner of a 1996 787 GTX. Only got two days out of the thing before it broke. I have no spark to both spark plugs and have been trying to locate the issue. The ignition coil passes the static test and I have to the best of my ability checked all ground connections and fuses.

The engine cranks as if it wants to start but there is no spark. Should I disconnect the mpem and check the resistances? I tried quickly to disconnect the mpem butt connectors but had difficulty. Any suggestions how to disconnect these?

All help/advice is mush appreciated!!!

There is a second ground, a very thin black wire that come out the rear elec box and connects to the battery, is it intact? The cdi wont fire with out it. A broken trigger coil causes no spark also, but its a pain to get to with out pulling the motor.

Thank you for the help. The small ground is intact. I was hoping to avoid removing the cover to get to the trigger coil. Is there a way to determine this is faulty without using the testing harness the manual refers to?

The thing is if the brace that holds it is broken (common failure) it might test ok but still not work.
this might help you.
