Hi, Wondering if anyone has a wiring diagram for a 1978 OMC 307, 225 HP 800. I have replaced the alternator with a new 1 wire 60 amp unit. I am replacing the wiring from the alternator to the amp meter(6ga)(replaced with new also) and back to the starter(6). It looks like someone has been into it before, can't find any fuse locations except for 20 amp glass fuse holders under the console which are a 20 amp between amp meter and ignition and another 20 amp between ignition and accessory panel. Logic tells me there should be a fuse or link between the alternator and amp meter and another between amp meter and starter but I may be wrong. My seloc manual seems to be missing after moving. If no one has a diagram maybe some insight on fusing will help. Thanks in advance. Ahh, almost forgot. The new alternator is internally regulated so I think I will have to connect the purple wire coming out of it to a new 12 volt source, I think??
