Electrical System
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). Always check the item being
tested and the harness connector for damage or corro-
sion and clean or repair as necessary.
CAUTION
When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
Fuses
A group of fuses are used to protect the 12 VDC and 48
VDC systems and are located under the seat assembly
(Fig. 19). All fuse block fuses are rated at 80 VDC.
The12VDCfusesprotectcircuitsasfollows:
The 5 amp fuse is used to protect the power supply
to the optional USB charger port circuit. and power
point.
The 10 amp fuse is used to protect the power supply
to the headlights circuit.
The 15 amp fuse is used to protect the power supply
to the optional power point circuit.

The 2 amps fuse is use to protect the power supply
to the display (Fig. 20).
An additional fuse is attached to the controller (Fig. 21).
This fuse is rated at 425 amperes continuous and pro-
tects the 48VDC vehicle power supply circuit. If this fuse
has failed, vehicle operation will not occur.
IMPORTANT: If fuse replacement i s necessary on
your Workman GTX Electric vehicle, make sure that
new fuses h ave the correct specifications (voltage
and amperage).
