Ok! I have a question for you ole' experts out there. I have a Gray Marine Phantom 45 (freshly rebuilt) that I want to install into a home made 14 foot runabout. I had the starter and generator re-built as well. I had asked the generator shop to re-wind the generator to 12 volt for obvious reasons. They tried however couldn't get the proper field coil. They said that it couldn't be done on that generator. Since this generator is special with an output shaft for powering the water pump it is not practical to mount an alternator in its place. All right, here is the question;
Can I connect a 12 volt regulator to this generator, start and run the engine on the battery at idle and will the generator develop enough voltage to re-charge the battery at cruising rpm (say about 2400 or so)? Any thoughts?

No that won't work. The most you can turn up the regulator is about 9.4 volts.We used to do this and use an 8 volt battery on hard starting tractors.If you didn't put a resistor in the wireing to the coil you got short life of points condenser and coils. If you had a magneto it didn't matter.

Use 2-6 volt batteries connected in series to turn the starter over and have them wired in parallel from the generator for charging.

I (sort of) faced a similar challenge and I wrote up a short note on that subject;
I think that would do the trick - it has worked well for me for over 15 years.
