[C320-list] High Efficiency Alternator

[Chris Burti]

Bob, Jeff,

What is the OEM wiring gauge in the run from the alternator to the
batteries and what did you move up to?

Pat,
If you make this upgrade, give me a call. I will try to make time to
give you a hand and we can take some photographs and do a writeup for
the website and Mainsheet.
