Non-Wired MPEM Ignition Module 5A Test
If your 5A fuse is blowing on your non-wired plug in mpem then the chart below will tell you where to connect power to see if the mpem is faulty. Note to bench test the mpem you’ll need to first label and unplug all harnesses. Then you unbolt the mpem from the bracket and remove from the watercraft. Once on a bench, insert a good 5A fuse in the proper location. The positive and negative always connect to one of the spade terminals and those are labeled 24/25/26 in each plug. Then using the connect info below, first connect ground to the proper plug and terminal. Then connect positive to the other terminal. If the fuse pops your mpem is faulty. If not, you’ll need to determine what other problem in your electrical system is blowing that fuse.
As an example, if the connect info was 3-26… The image below shows plug 3 which is the first number in the connect info.
The image below shows connector 26 which is the second number in the connect info.
