Then connect small leads to the
battery and press (Y Enter).
If all connections are correct, wait
for a load to be applied.
The results will vary depending
upon and the conditions of the
cables. Both the positive and
negative circuit results will be
indicated from the single test.
Select LIFTGATE CHARGE,
LIFTGATE MOTOR or LIFTGATE
TRUCK CIR. to perform a voltage
drop test on the trailer charge
circuit, trailer liftgate motor circuit
or the truck’s liftgate power circuit
respectively.
The liftgate charging circuit includes the positive cables from the front of the
trailer to the liftgate batteries and the negative cables and/or frame from the front
of the trailer to the liftgate batteries.
The liftgate motor circuit includes the positive cables and the solenoid from the
liftgate batteries to the liftgate motor and the negative cables and/or from the
liftgate batteries to the liftgate motor.
The liftgate truck circuit includes the positive cables and the negative cables and/
or frame from the trucks batteries to the font of the trailer (end of the “stinger” cord).
Adapters are available from Auto Meter to facilitate connecting the BVA-2100 to
single pole and dual pole connectors on both trucks and trailers. See the manual
supplement that is included with those adapters for more detailed information on
testing and trouble shooting the liftgate charging circuits and liftgate motor circuits.
If the overall voltage drop is not within the desired specifications the small leads
can be moved closer along the line being tested and the test run again (see
dotted lead on previous page). If the results are desirable, it is the section not
included in the last test. If the results are not desirable the problem is most likely
in the section being tested. Repair and test the entire section again.
