Correct Coach Battery Wiring

[Jeff Miller]

Not to get into the '81 battery wiring right now, ... but a couple of
things: The boxes/taped wires are for the battery heaters.

The chargers are powered when running on genset, but not on shore
power? Sounds like either your shore cord or your transfer switch is
not powering half of the coach. Check power at all circuits and at
the two mains in the breaker panel, check for two hot and one neutral
in the coach-end of your power cord. For a temporary fix, open the
charger bay, plug the chargers directly into your house power.

Based on the symptoms mentioned here it doesn't sound like the
battery wiring is a problem.
