hello everyone.

I have one MARINER MERCURY 40 HP ELPTO 3 CYL, and my issue is that I only get spark on the top spark plug and not on the other ones. The stator and the CDM are alright. Everything indicates that the failure is located at the Revolution limiter. Is there a way to bypass this box? thank you very much.

Unplug the sparking CDM and retest for spark on the others.

One bad CDM can block spark on the others.

Check the CDI Ignition Troubleshooting Guide for detailed testing to isolate and prove the fault in the system.

Remember, NO RETURN on electrical parts, test and PROVE the fault before ordering anything.
