Glow and Power Relays
The Groundsmaster 4100--D uses two (2) identical re-
lays to control electrical power circuits. The glow relay
is attached to the the right side of the fuel tank support
under the hood. The power relay is attached to the con-
trol panel under the console housing.

The glow relay supplies electrical power for the engine
glow plugs when energized. The start relay is energized
by the glow plug controller.

The power relay supplies electrical power for fuses F9
(TEC--5002 outputs), F10, F11 and F12. The main pow-
er relay is energized when the ignition switch is in the

NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5
ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.

At only 700mm wide the Mini Dumper is even at home on tight access
sites. No need to grunt, groan, and force the
mower about the yard. The US will be getting a revised 2011 Jeep Wrangler but the diesel option will not be offered in the United States.
