Diode Assembly
A diode assembly is included in the Workman GTX Elec-
tric wire harness. This d iode is used for for circuit logic
to allow key switch current to the controller. The diode
plugs into the wire harness near the vehicle fuses next
to the on--board battery charger.
The diode assembly can be identified by a black color
and a diode symbol on the end of the diode assembly
body (Fig. 48). Refer to the wire harness drawings in
Chapter 6 -- Electrical Drawings for additional informa-
tion on diode assembly location.
NOTE: If a vehicle is equipped with the optional brake
and turn signal kit that includes flashers, four (4) addi-
tional diode assemblies are used for hazard light and
turn signal circuit logic. These diodes plug into the brake
and turn signal kit wire harness and can be accessed by
raising the hood.
Testing
1. Park vehicle on a level surface, turn key switch to
OFF, engage the parking brake and remove key from
the key switch.
2. Locate diode assembly that is to be tested.
3. Remove cable tie that secures diode to wire harness.
Unplug the diode from the wire harness for testing.
4. Test diode assembly using a digital multimeter
(diode test or ohms setting) and the table in the right col-
umn.
5. If testing determines that a diode assembly is faulty,
replace diode assembly.
6. After diode testing is complete, make sure that diode
assembly is fully installed into wire harness connector
and secured to harness with cable tie.
