The 12v alternator that came on my Yanmar110 has a ground wire, but it is grounded to the block. I think I will be able to use it. The 24v alternator that was in the old Volvo is also an isolated ground, but has been grounded to the non-isolated Yanmar ground wire thus far. Once I get the harness built, install the new switches, senders, and solenoids, both alternators and the senders will be grounded back to the negative on the battery side of the solenoid. The solenoid will make the connection of the engine block to the negative battery post only when the engine is cranked or when the STOP button is pushed. When the engine is stopped or running, the connection is interrupted by the solenoid.
It'll make more sense when I get the isolation schematics to you.

Thanks Kent. You are a wealth of knowledge on this subject, and a great resource for the group. I'm curious, is your alternator an isolated ground alternator? Also, what gadget do you have to measure hull potential, as I need one. I will admit that your experience has scared me a bit.
On another subject, do you happen to know the pitch marks for your max prop? I've got the same prop, and suspect I'll need to adjust the pitch for the higher revving Yanmar.
