WARNING
There is battery
voltage
at the PCB
at all times.
Failure to disconnect
battery cable will result in damage to
equipment
or injury to personnel.
Check the wires and connections
at both ends for
broken wires or any kind of bad connection.
Repair whatever
you can.
If the wires and
connections
seem ok, you have to replace the
harness.
Repair wiring or replace harness (para. 4-80).
