Component Testing

For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. disconnect the harness wire connectors
from the vehicle key switch before doing a continuity
check on the key switch).

Key Switch

The Workman GTX Electric key switch has two (2) posi-
tions (OFF and ON) and three (3) switch terminals on the
back of the switch. The key switch is located on the dash
panel.
NOTE: Only key switch terminals B1 and 3 are used on
the Workman GTX Electric vehicle.
NOTE: The Workman GTX Electric key switch circuit is
a 48 VDC circuit.
Testing
CAUTION
When testing the key switch for continuity with a
multimeter (ohms setting), make sure that power
to the circuit has been disconnected.
1. Park vehicle on a level surface, turn key switch to
OFF, engage the parking brake and remove key from
the key switch.
2. Make sure that vehicle battery charger IS NOT con-
nected to electrical outlet. Open the battery circuit by
disconnecting the conductors between the battery pack
and vehicle components (see Opening Battery Circuit in
the General Information section of this chapter).
3. Raise hood to allow access to wire harness connec-
tions for switches mounted in dash.
4. Label and disconnect wire harness connectors from
the key switch.
5. With the use of a multimeter (ohms setting), the key
switch functions may be tested to determine whether
continuity exists between the B1 and 3 terminals for
each switch position. The key switch terminals are
marked as shown in Figure 10.
Electrical System
When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
OFF
FRONT VIEW
A. When the key switch is in the OFF position, no
continuity (infinite ohms) should exist between
switch terminals B1 and 3.
B. In the ON position, continuity (zero ohms)
should exist between switch terminals B1 and 3.
6. Replace key switch if testing determines that the
switch is faulty.
7. If key switch tests correctly and circuit problem still
exists, check wire harness for possible problems (see
electrical schematic and wire harness drawing in Chap-
ter 6 -- Electrical Drawings).
8. After key switch testing is complete, connect wire
harness connectors to the switch.
9. Connect the conductors between the battery pack
and vehicle components (see Opening Battery Circuit in
the General Information section of this chapter). Make
sure to torque hex nuts on battery terminals from 95 to
105 in- -lb (10.8 to 11.8 N- -m).
10.Lower and secure front hood.
