Sorry for the delay, I am suspectin that the low voltage disconnect circuit may be at fault.
NOTE: If the LVD deactivates (removes power
to the cab/sleeper loads), it must be reset prior
to performing a functional test. If the batteries
are discharged below 12.3 volts, charge the batteries
before performing any troubleshooting
procedures. The LVD can be reset by starting
the engine. Once the LVD senses 13.1 volts or
more, it resets automatically.
1. Shut down the engine.
2. Unplug the 10-position connector from the LVD.
3. Remove the wire from cavity E on the connector,
and wrap a small piece of electrical tape around
the exposed wire.
4. Insert the connector into the LVD with wire
BA22D still removed.
NOTE: The red LED indicator light on the LVD
should turn on when the connector is inserted.
5. Insert a metal conducting probe into cavity E of
the connector, making sure contact is made between
the metal probe and pin E on the LVD.
6. Connect a jumper wire between the terminal on
wire BA22D and the test probe inserted in cavity
E.
NOTE: The electrical loads, such as interior
lights, will remain OFF even though an electrical
connection exists between circuit BA22D and
pin E. The LVD needs to be reset after removing
the plug from the LVD.
7. Reset the LVD by starting the engine. The dome
lights should come back ON, and the red LED
indicator light on the LVD should turn OFF.
8. Shut down the engine.
9. Remove the metal test probe from cavity E.
NOTE: After removing the test probe, there will
be a delay before the LVD disconnects the cab/
sleeper loads. If equipped with the optional
warning buzzer, it will sound for 60 seconds.
After the time delay, the cab/sleeper loads
(dome lights, for example) will shut OFF, and
the optional warning buzzer will shut OFF.
10. Disconnect the jumper wire from BA22D.
11. Remove the 10-position connector from the LVD.
12. Insert wire BA22D into cavity E of the connector.
13. Insert the connector into the LVD.
14. Start the engine to reset the LVD.
15. If the LVD does not operate properly after performing
the functional test, perform the troubleshooting
procedures. We need to check this so we can continue on.
