110v charging system (task)

Under the port side bench in the main cabin (forward of the nav station, aft of the freshwater tank) is a unit that appears to be a battery charger for when the boat is hooked to shore power.

Ted disconnected it from the 12v system when he repaired the alternator.

Someone needs to:

1. look through the manual to see how it works
2. verify how it should be connected to the 12v system
3. verify that it is properly connected to the 110v system
4. power it up to see that it works
5. if it seems to work, re-connect it to the 12v system
6. verify that it charges the batteries properly
7. document how to use it for future reference.
