Troubleshooting
PROBLEM: Unit will not power-up (no ready light).
PROBABLE CAUSE: No +12VDC to the Supervisory Control Module.
Low Battery voltage.
SOLUTION:
1) Check the 5A fuse for continuity, replace if necessary. (part # 70946)
2) Check battery voltage to the Supervisory Control Module at TB1 # 2 using TB1 #3 as a DC
ground. While LectroCount
3
will power-up at 10VDC, it is recommended that the input be at
least +12.6VDC or higher. Refer to the LectroCount
3
installation manual and wiring diagram for
more detailed information. If voltage is not present, inspect the battery cable (part # 81232) for
damage.
3) Check the 7.5A in-line fuse (part # 70985) (located near the positive battery terminal) for
continuity and replace if necessary.
4) Check the accessory line voltage at TB1 #1 using TB1 #3 as a DC ground. The DC voltage
should be +12VDC or higher. If the voltage is present, (ignition key in accessory) replace the
power supply board (part # 81213). If voltage is not present, trace the accessory line back to its
source, inspecting any in-line fuses for breaks.
PROBLEM: Unit blows 7.5A fuse.
PROBABLE CAUSE: +12VDC Battery line shorted to ground.
SOLUTION:
1) For safety reasons, Remove the 7.5 Amp in-line fuse from the battery cable (connected to the
positive battery post)
2) Remove the 3-pin power connector (TB1) and inspect for stray wire strands and visible shorts.
3) Inspect the full length of the battery cable, looking for damaged insulation which may cause
shorting between the cable and ground potential (i.e.: truck frame, chassis) If the battery cable
is damaged, replace it. (part #81232)
4) Replace the 7.5 Amp fuse (part # 70985)
PROBLEM: Unit blows 5.0A fuse.
PROBABLE CAUSE: Excessive current on 5A circuit.
SOLUTION:
1) Remove the cable marked PRINTER POWER from the rear panel of the EPSON printer and
replace the 5A fuse. (part # 70946) If the READY light remains on, replace the EPSON
printer.(part # E4900-1) If the 5A fuse blows, replace the printer power cable (part # 81233). If
the 5A fuse continues to blow, replace the power supply board. (part #81213)
