[C320-list] Xantrex shore charger

[Myron Welch]

Jeff,

My smaller wires are from the charger to the battery, not the battery 
to the starter.  I wish I could give you the size, but the boat and 
owner's manual are in cold storage in northern Michigan.  Should 
those be changed to the larger size wire on the newer boats?

Thanks for all your help.  I think we should all take a week long 
electrical systems seminar with you.  I would enjoy that.
