Thanks!

Could the 4th be the shore batt'y charger? if so one option might be to move that to the batt'y post of the sel sw... that's how mine is wired

I read this re: batt'y corrosion - interesting but I'm not an expert and haven't heard this before...

"Corrosion on the terminals is due to hydrogen gas being released from the acid in the battery. It mixes with other things in the atmosphere under the hood and produces the corrosion you see on the terminals. Generally, if the corrosion is occurring on the negative terminal, your system is probably undercharging. If on the positive side, it is probably overcharging. Most often it will be seen on the negative side because the battery is usually in an undercharged situation. This is just the nature of the beast, I'm afraid."
