Headlight Switch (Groundsmaster 4110--D)
The Groundsmaster 4110--D headlight switch is a two
(2) position rocker switch that is located on the inside of
the control arm (Fig. 46). Theheadlight switch allows the
headlights and taillights to be turned on and off.
Testing
1. Make sure ignition switch is OFF. Remove key from
ignition switch.
2. Disassemble control arm to gain access to headlight
switch (see Control Arm in the Service and Repairs sec-
tion of Chapter 7 -- Chassis).
3. Disconnect harness electrical connector from the
headlight switch.
4. With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
switch position. The switch terminals are marked as
showninFigure47.Thecircuitryoftheswitchisshown
in the chart below. Verify continuity between switch ter-
minals. Replace switch if testing identifies a faulty
switch.
