Universal M-12 alternator and starter wiring
This is a little embarrassing. (Happens to me a lot.) I did a lot of work to my Universal M-12 over the offseason on my new-to-me Pearson 27 (first diesel for me), including pulling out the alternator and starter and getting them rebuilt. I usually do a good job of taking pictures and labeling things, but not so good here, in part because I knew I had the service manual with wiring diagram. Now I'm trying to put everything back together.
My alternator has connections POS, NEG, REG, AC TAP. I know what AC TAP is for and I don't have a tach, and REG is connected to the included regulator. I have the standard wiring harness with the trailer light connectors. I know the dangers (from Mainesail and others), and I've read how to fix it. Part of this project is to get rid of those, but I just want to briefly get back to the stock, working condition. Wiring diagram from service manual is attached. So #4 goes to POS on the alt. Where does #11 (jumper from alt to starter positive) go? In the diagram, it is labeled "Sense" on the alt? Does anything get connected to NEG on the alt? Right now, #1 is connected to the engine block. Should #1 go on NEG on alt?
