STARTING SYSTEM MAIN CABLE VDROP™
TEST
The circuit from the battery to the starter junction is being tested.
Note:
If a split battery bank is used go to the Generic Starter Drop Test
and perform a split battery procedure. See section 11. By disconnecting
each bank and testing the other using the Generic Voltage Drop Test and
entering one half the starter draw you can test the starter main cables
individually. First of all determine if the system you are going to test is a
“split” or “single” system.
This test can be selected from the
main menu by selecting VDROP
MENU then by pressing (Y Enter).
…select >STR. MAIN CABLES
and press (Y Enter).

STARTER TEST
The various liftgate circuit voltage drop tests and the generic voltage drop
test can be used to test the liftgate charging and motor circuits as well
as any other circuit that includes a battery and cables and is designed to
operate a load of 20 amps or more.
Select TRAILER CHARGE, TRAILER MOTOR or TRUCK CHARGE 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 frame 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 BCT-200J 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.
Using the (+/-) key adjust Amp
rating to that of the generic load
device.
Connect large leads to the generic
load.
