Testing the Fuse
1.
If necessary, see Testing Basics on page 12-12.
2.
Access the fuses but do not remove them. Fuses are found at the following locations:
–
On Controller Mounting Plate:
15-amp fuse to DC/DC converter, 2-amp fuse to connected car device
(Guardian/Visage V3 Circuit), and 15-amp fuse to electric powertrain
–
Under Floorboard Near MCOR:
20-amp fuse from DC/DC converter to accessories
–
Under Front Cowl:
15-amp fuse to cab, 10-amp fuse to brake lights, horn and turn signals, 7.5-amp fuse to
headlights and taillights, 10-amp fuse to 12-volt power strip and power point
–
On Main Harness Near Controller Mounting Plate:
30-amp fuse for charger receptacle harness
–
On Main Harness Forward of the 30-Amp Fuse:
1-amp fuse for charger interlock circuit
3.
2-Amp and 15-Amp ATC Fuses On Controller Mounting Plate and 30-Amp ATC Charger Receptacle Fuse:
With the batteries connected and the Run/Tow switch in the RUN position:
3.1.
Probe the two, small metal contacts on the top of the fuse
3.2.
Each contact should show BPV.
3.3.
If only one side shows BPV, replace fuse.
3.4.
If neither side of fuse shows BPV, do the following:
– Check BPV.
– Check condition and connection of large red wires at solenoid.
– Check sonic weld_8 in main wire harness.
– For one of the 15-amp ATC fuses, check Run/Tow switch to make sure it is in RUN position.
– Check if 12 gauge red wire is coming off large post on solenoid.
4.
1-amp AGC Glass Fuse Only:
With the Run/Tow switch in the RUN position:
4.1.
Probe the wire on each side of the fuse with insulation-piercing probes.
4.2.
Each probe should show 42 to 46 volts.
4.3.
If only one side shows voltage, replace fuse.
4.4.
If neither side of fuse shows voltage, do the following:
– Check Run/Tow switch to make sure it is in RUN position.
– Check diode_1 in main wire harness.
– Check 10k ohm in main wire harness.
– Check 15-amp ATC fuse on controller mounting plate.
