DIRECT DIAGNOSTIC GUIDE
REFERENCE #2
No LED: Open circuit between liftgate battery positive or liftgate
battery ground and the Direct Controller. Follow the steps below
to diagnose the No LED Status (see Figure 5).
1. Using a voltmeter, measure the voltage between the positive
post and the negative post on the liftgate battery (see V1 in
Figure 5). If the reading is less than 12.0 V, charge or replace
the batteries. If the battery is higher than 12.0 V, move to step
2.
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. Reset the circuit breaker or repair/replace the
wire. If there is battery voltage, move to step 3.
3. Using a voltmeter, measure the voltage between the ground
stud from the 7-way and the liftgate battery positive stud
inside the Direct 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 Direct Contoller. Once these steps are completed, if
there are still no LEDs, call customer service, as the Direct
Controller may not be functioning properly.
STINGER/AUX DIAGNOSTICS
Plug in the stinger and start the tractor (see Figure 6 for location
of Source LED; see Figure 7 for LED status reference, located on
right side of Direct Controller).
