16. Measure the resistance between the white insulated ground stud and the liftgate battery ground. (See figure
#6 – Ohm 3) It should read zero. If yes, continue to step 17. If no, repair or replace the white wire between
the white insulated ground stud and the liftgate battery ground.
17. Measure the voltage between the #1 pin of the four pin Deutsch plug and the white insulated ground stud.
(See figure #6 – V17) It should read more than 13.3 volts. If yes, continue to step 18. If no, repair or replace
the black wire between the black insulated stud and the #1 pin of the four pin Deutsch plug.
18. Measure the voltage between the #4 pin of the four pin Deutsch plug and the white insulated ground stud.
(See figure #6 – V18) It should read battery voltage. If yes, continue to step 19. If no, the issue is the green
wire between the ignition junction stud (the second stud from the top on the five stud junction strip) and the
#4 pin of the four pin Deutsch plug, repair or replace this wire.
19. Measure the voltage between the white insulated ground stud and the #2 pin of the four pin Deutsch plug.
(See figure #6 – V19) It should be the same as the liftgate battery voltage. If yes, continue to step 20. If no,
check to see if the fuse cube is blown. (See figure #6 – arrow) If blown, check the wire between the #2 pin of
the four pin Deutsch plug and the fuse cube to ensure it is not grounded. Repair or replace wire, then replace
blown fuse cube.
20. Plug in the four pin Deutsch plug into the Trail Charger four pin Deutsch receptacle. (See picture #7) The
green LED light should illuminate. (See picture #8) If yes, input testing of the seven-way is complete, proceed
to the Trail Charger output troubleshooting section. If the green LED does not illuminate, the Trail Charger is
defective and needs to be replaced. If the LED light on the Trail Charger blinks green once, red twice, and
repeats, there is excessive voltage drop under a load between the tractor/power source and the trail charger.
Testing the output of the Trail Charger
1. Measure and record the voltage of the liftgate batteries before you turn on the Trail Charger. (See figure #7 –
V20) __________volts with no charging. It is highly suggested the liftgate batteries be tested and at least
12.35 volts or higher before testing.
2. Turn on the Trail Charger by connecting a power source to the combo nose box or seven-way nose box.
