Chuck, thanks ever so much for the excellent article on the Universal diesel engine harness upgrade. Alianna has an M4-30 which has exactly the engine panel shown in the photo and the wiring harness is also as described. I have noticed a low charging voltage so I removed the alternator and had it shop tested only to find out it was working properly. Now I know more about the source of the problem and rewiring that system will be first on my to do list next spring. The instructions in the article make it seem like I should be able to do this myself. I also noticed that when starting the motor my chart plotter, if on, always turns off and then restarts...I am hoping that fixing this dangerous wire harness issue will resolve that problem too.
