I'm the new owner of a 2003 Tiara 31 open,  The boat has the Cummins 330 engines, with non regulated Balmar alternators.  There is a Charles Regulator controlling them.  Here's the question, on the electric panel inside there is a AC breaker labeled  charger with a 12awg black wire coming off of it .  I have looked everywhere without finding a charger.  Also if I watch the DC meters I don't see a rise in DCV when the charger switch is turned on.  The Charles regulator is supposed to be turned on by the ignition so I don't think that is the purpose of the switch.  I'm thinking of installing a charger but what worries me is that AC switch, I've tried to trace it but it's impossible.  Any ideas how these boats were equipped, it seems odd to me that there is no battery charger.

On my previous 03 35 Open, the Charles-C Charger (alternator regulators) was located in the engine compartment - there is no switch to turn them on/off as they are controlled by ignition.

The "battery charger" on the AC panel in the cabin is for the normal battery charger when the shore connection is connected.  On my 35 Open, this charger was located underneath the AC panel in the compartment where the water heater is (accessible by removing the wood panel behind the dinette seating).

You need to make sure you have the correct shower power connecting breaker on to run this charger - it was SHORE POWER 1 on my boat.  You will likely hear the small fan turn on and see the DC voltage gauges go up when it is powered up.

You were right on, on the 31 there is a teak finish vertical panel behind the setae cushion.  Inside was the charger (30 amp Charles), a audio amp and some real neat looking wiring.  Thanks for the help.
