Command Engage switch - Short circuit to ground (K.25.E.05.83 -
G.30.B.53)
AFX8010
E0036-04 - Feeder CVT Pump Voltage Supply
Cause:
Low battery voltage to CCM1 through the feeder engage switch S-31, or the Feeder CVT Pump Voltage Supply
circuit is shorted to a ground.
Possible failure modes:
1.
Loose or corroded connections, or damaged wires.
2.
Batteries are discharged, and/or alternator/regulator failure.
3.
Supply wiring shorted to ground.
4.
Controller internal failure (internal regulator failure).
Solution:
1.
Key switch in "Off" position. Check fuse F42.
A.
If fuse F42 is okay, continue with Step 3.
B.
If the fuse is blown, go to Step 2.
2.
Replace the failed fuse F42.
A.
If the fuse is okay, continue with Step 3.
B.
If the fuse immediately fails again, a short to ground exists in wire 010 red to Cab Power Relay K26 pin
3. Locate short and repair.
3.
Key switch in "On" position. Check fuse F48.
A.
If fuse F48 is okay, continue with Step 5.
B.
If the fuse is blown, go to Step 4.
4.
Replace the failed fuse F48.
A.
If the fuse is okay, continue with Step 5.
B.
If the fuse immediately fails again, a short to ground exists in one of the following wires:
- wire 109 orange, fuse F48 to relay K28, terminal 3
- wire 108 orange, fuse F48 through connector X001 pin 3 to RH harness splice
- wire 358 orange, RH harness splice to feeder engage switch S-31 connector X056 pin 2
- RH console power wires to propulsion handle S-03, front switch panel A-13, rear switch panel A-18
and RHM connector X026 pins 4 & 5
- wires 300 orange, 110 orange & 1180 orange, RH harness splice across separator switch S-30 to
neutral switch S-02 connector X059 pin 3
Locate the short and repair.
5.
Move the separator engage switch S-30 to the ON position, and observe the fuse F48.
A.
If the fuse is okay, continue with Step 8.
B.
If the fuse immediately fails, a short to ground exists in on one of the following wires:
- wires 147 yellow, 111 yellow & 1061 yellow, separator engage switch connector X055 pin 6 to CCM2
connector X015 pin J1-7 and connector X012 pin J1-7
- wire 1212 yellow, separator engage switch connector X055 pin 3 to connector X012 pin J1-17
- wire 302 yellow, separator engage switch connector X055 pin 3 to feeder engage switch connector
X056 pin 5
Locate short and repair.
