Starting the Generator
AGS (Automatic Generator Start)
Your motorhome may have The Magnum® Standalone AGS system, which monitors your
battery system or surrounding temperature and starts the generator when the battery requires
charging or power is needed to run the air conditioner. The AGS system uses a remote
switch setup and does not use the standalone switch provided with the Magnum® system.
The AGS startup switches are typically located on the command center panel.
Manual Generator function
To start the generator manually, make sure the parking brake is engaged.
The ENABLE button (on the panel) is not used for manually starting the generator.
Press the START button until the generator fires, and the indicator light above the
switch comes on.
To stop the generator, press the STOP button.
AGS Controller
The AGS controller is typically located in a bathroom cabinet, and
is used to set the run time hours, start temperature, start voltage,
clock and the quiet time. For information on setting these controls,
refer to the Magnum® AGS owner manual.
Automatic Generator Function
Before using the AGS system set the motorhome parking
brake.
1. Press the momentary AGS ENABLE switch. The
LED indicator above the switch will light.
2. STATUS indicator will display one of three indica-
tions:
Blinking Green
– Indicates the system is initiat-
ing a generator start sequence (either the TEST or
ENABLE switch has been pressed).
Solid Green
– Generator has started successfully.
Solid Red
– After 4 attempts to start, there was a
“no start” indicating a problem with the AGS sys-
tem.
3. A generator “START/STOP” switch is installed on the command center panel. A sec-
ond switch is located on the generator, and depending on your motorhome model, there
may also be a switch installed on the dash.
4. At either “START/STOP” switch, press and hold the upper portion of the switch to start
the generator. Depending on the outside temperature, the start process can take up to 15
seconds. Once the generator starts running, release the “START/STOP” switch. The
indicator above the switch will light up.

Excessive usage can overheat and damage the generator starter motor. Do not
engage the starter motor for more than 20 seconds at a time. If the generator
doesn’t start after the first attempt, wait at least two minutes before beginning
another start sequence. If the generator does not start after a third attempt,
refer to the generator owner’s manual for additional information.
