Well today I removed a CMM 7000 EFI unit for random shutdowns.

Bench tested it under load untill it failed...

Showed a Code 47 fault. Did it more than once.

I checked the coil connections to the controller and all was fine as it always is...

Installed a NEW 300-5047 Controller and continued to test the unit...

Ran the rest of the day on and off with various loads applied and no more shutdowns...

So for the umpteenth time a controller is at fault and the fault code it showed was somewhat misleading.....

And during the time I worked on this unit another customer came in with a similar problem......He may or may not be getting a controller also but he opted for a wait and see deal as we cleaned some wire connections....

My money is on him returning before the week is out to get the controller replaced.....and regretting not doing it today.......
