ELECTRICAL SYSTEM

12 VOLT OPERATION
The major portion of electrical power in your Airstream is 12-volt. The 12-volt current
powers the exterior and interior lights, water tap system, cook top igniter, ceiling fan,
TV Antenna Amplifier, and 12 volt power ports for optional equipment.
All 12-volt current comes through the converter/battery system. The battery is acces-
sible in the battery box attached to chassis frame rail under the front of the trailer. A
galvanized cover protects the battery. Inside the cover are two weather proof inline
fuse holders. Just in front of the same chassis frame rail is a 40 amp fuse protecting
the circuit from the battery to the converter.
A black box on the front of the same frame rail is the 7-way cord distribution center.
The two inline fuses are a 15 amp fuse going from the battery to the breakaway switch
on the trailer tongue and a 30 amp fuse goes from the battery to the 12 Volt battery
charge line in the 7-Way tow vehicle plug.

BATTERY DISCONNECT SWITCH
The battery disconnect switch is used to separate the battery from the 12-volt distribu-
tion panel and converter charging system.
When the switch is turned on and the trailer is plugged into a 110-volt shoreline, the
12-volt distribution panel will receive power and the battery will be charged through
the converter.
When the switch is turned to off and the trailer is plugged into a 110-volt shoreline, the
12-volt distribution panel will still receive power from the converter, but the battery is
disconnected from the converter and will not be charged.
When a shoreline is not available or the unit is being stored, turning the switch to the
off position will prevent parasitic draws from discharging the battery.
The charge in the 12-volt batteries is replenished from the tow vehicle alternator
through the 7-way cord. This charge will go to the battery no matter which position the
Battery Disconnect Switch is in.
