SELECT DIAGNOSTIC GUIDE
Step 2: Using a voltmeter, measure the voltage between the
positive and negative studs on the plate inside the battery box
(see V2 in Figure 5). If there is no voltage reading, the issue is
either the circuit breaker or the wire from one of these studs to
the circuit breaker. Replace the circuit breaker or repair/replace
the wire. If there is battery voltage, move to step 3.
Step 3: Using a voltmeter, measure the voltage between the
ground stud from the 7-way/reefer and the liftgate battery
positive stud inside the Select Controller (see V3 in Figure 5).
Liftgate battery voltage should read 12.0 or higher. If not, check
the 2-amp fuse and replace if necessary. If there is still no
voltage reading, repair or replace the wires between the battery
box and the Select Controller. Once these steps are completed,
if there are still no LEDs, call customer service as the Select
Controller may not be functioning properly.
STINGER DIAGNOSTICS
Unplug the 7-way, turn off the reefer, plug in the stinger, and
start the tractor (see Figure 6 for location of Stinger LED; see
Figure 7 for LED status reference, located on right side of Select
Controller).
