OK I have a mid 70 mercruiser 140 that I think the alternator has giving the ghost up. I just used the pontoon last weekend and noticed at first start my volt gauge would read battery voltage till i reved it bast 1300 rpms then it would jump up to 14.0v. Tonight I was finishing up on my fuel system hooked the muffs up and noticed the alt. not charging at all. This is a single wire alternator with just a red(bat) wire going to it.
I'm almost positive the alt. finally gave out but I just want to make sure before I go and buy a MARINE alt.
Thanks
Mike
