OK, I posted previously that my volt gauge is reading 12 to 12.2 volts. I looked at my diagram fro my 69' Merc 800 and it shows three wires going to the rectifier. Two from the stator and one positive cable in the middle. I look at my rectifier and I have four wires going to it. Is one of those running to the volt meter. Also, at least according to the wiring diagram, it doesn't matter what way the wires from the stator hook-up tot he rectifier. Is this correct? I have another rectifier that I want to try out, I just want to make sure that the original is hooked-up correctly. Last year, when I had the boat out, it was charging. Also, how difficult is it to change out a stator on one of these engines? Thanks all for any info.
