MPEM Ignition Module Test Data Sheet
The information below is used in testing your MPEM (multi-purpose electronic module) to verify that it is within published Sea Doo specifications. Even if it does check out ok, sometimes the MPEM can fail when under operating conditions so take that into consideration when diagnosing problems. When checking your MPEM, make sure to use a digital ohmmeter which has known accuracy. Also, to avoid ohmmeter damage and to get accurate results, MPEM testing must be done with all wires disconnected from circuit. Finally, note that most MPEMs after 1996 can’t be tested due to their complicated internal circuits. I’ll periodically update this site so if you need test data for one not listed, let me know.
