MLC-1 Troubleshooting
•
Error Code:
If the MLC control senses a fault, an LED indicator will show a quick repetitive flash. See
display below for flashing LED error code
LEDs do not light:
1)
If terminal #7 is connected to a switched 12/24vdc source from the ignition key
switch accessory terminal or a spare accessory switch. Make sure this switch is
on.
2)
Test voltage at terminal 7 (green plug) which should be 12 or 24vdc. This
terminal must be connected to the ignition key switch or accessory switch. Turn
key switch or accessory switch to ON and make sure battery selector switch is
turned on.
3)
Measure voltage at terminal 1 (green plug) (+12 or +24vdc) and terminal 2
(battery negative) for proper voltage (see wiring diagram). Replace fuse or
repair poor connection if battery voltage is not measured at terminals 1 and 2.
