3. Place a clip on ammeter around the red lead between pin
#2 of the four pin Deutsch plug and the fuse cube connected to the liftgate battery positive. (See picture #9)
Should read current. If yes, the Trail Charger is operating. If zero the Trail Charger is defective and needs to
be replaced.
Note: If you do not have a clip-on ammeter, use a voltmeter to read voltage when the Trail Charger is
operating. You should see considerably higher voltage.
Testing the brake lock out
1. Plug the six-pin connector into the Trail Charger. (See picture #10) Apply the brakes on the tractor. Green
LED light should blink slowly and the Trail Charger should turn off when the brakes are applied. Release the
brakes and the green LED should turn solid green and the Trail Charger should turn on. If it does the above the
brake lock out is functioning correctly. If no, continue to the next step.
2. Unplug the six-pin connector. (See picture #11) With a voltmeter measure the voltage from pin #2 of the six-
pin connector to the white insulated ground stud. (See figure #8 – V21) It should read voltage only when the
brakes are applied. If you have voltage when the brakes are applied and do not when they are released, you
are getting the proper signal and the Trail Charger is defective and needs replaced. If no voltage when the
brakes are applied, check the seven way nose box. The orange wire that connects to the brake circuit is fused
with a 2 amp in-line fuse in the seven-way nose box. (See figure #8 – arrow) Repair or replace the defective
portion of this circuit.
