TROUBLESHOOTING
PROBLEM: Unit blows 1.0A fuse / Lap-Pad is blank.
PROBABLE CAUSE: Excessive current on 1 Amp circuit
SOLUTION:
Isolate the problem by disconnecting the following devices until the problem is resolved. After
removing each device, re-install a fresh 1Amp fuse.
Lap-Pad: Disconnect the Lap-Pad from the Supervisory Console. Replace the
1)
fuse. If the fuse remains intact, this may indicate a defective Lap-Pad. (part#
E4030-1) Swap the suspect unit with a known working unit for verification.
Ram-Card: Remove the Ram-Card from the Ram-Card module. Replace the
2)
fuse. If the fuse remains intact, this may indicate a defective Ram-Card. (part #
E4101-X) Swap the suspect unit with a known working unit for verification. (part
# E4101-X)Verify also that the ribbon cable located on the rear of the Ram-
Card module (part # 81248 ) is not damaged.
Odometer Cable: ( if equipped ) (from 10-pin connector
3)
Supervisory Console) Replace the fuse. If the fuse remains intact, this may
indicate a defective odometer assembly and cable. (part # 821251) Replace
the assembly with a known-working unit for verification.
Pulser Assembly: If after replacing the above units the fuse continues to blow,
4)
it is possible that the pulser assembly is defective. Replace the pulser board
(part # 811521 for internal pulser, part # 81159 for POD type pulsers) with a
known working pulser. Note: For dual-meter systems, it is important to note
which pulser may be causing the problem. Always check the METER 1 and
METER 2 LED indicators on the Dual Meter Switch Box to determine which
pulser may be at fault.
PROBLEM: "Power Loss Stop" appears on Lap-Pad.
PROBABLE CAUSE: Power to LectroCount
SOLUTION:
1) Check battery and accessory cables for damage. Ensure that the Battery, Accessory, and
Ground wires on power connector TB1 (rear of supervisory console) are secure.
2) Turn on all truck accessories. (headlamps, 2-way radio, heater, etc.)
and monitor DC voltage at TB1 #2, using TB1 # 3 as a ground. If the voltage drops below +10
VDC, the truck electrical system may not be adequate to handle the current load for the
3
LectroCount . It may be necessary to upgrade the electrical system to accommodate the 5
Amp LectroCount³ current requirements.
3) Verify proper grounding of
