Troubleshooting the input (dual or single pole) portion of the charging system (No load)

1. Plug the dual or single pole stinger cord into the combo nose box on the front of the trailer. (See picture #1)

The tractor must be running or you can use a combination of a battery and a battery charger. Note: if you

utilize the latter, it must be able to provide 13.5 to 14.5 volts and up to 25 amps when loaded and still

maintain the correct voltage levels.

2. Unplug both the four-pin Deutsch connector and the six-pin connector from the Trail Charger. (See picture #2)

Steps 3 to 12 are with no load (zero current flow)

3. With an ohmmeter or continuity tester, measure from the white ground insulated stud and the liftgate battery

negative stud. (See figure #1 – Ohm #1) It should read zero on ohms and buzz on continuity. If yes, continue

to step 4. If no, check both connections to see if they are tight. If that does not fix the issue, repair or replace

the wire as necessary.

4. With a voltmeter (Do NOT use a test light) measure the voltage from the black insulated stud to the white

insulated stud. (See figure #1 – V1) Should read more than 13.3 volts. If yes, continue to step 5. If no, repair

the circuit from the combo nose box on the front of the trailer to the black and white insulated studs in the

battery box. The yellow LED light illuminated indicates there is power and the fuse is not blown.

5. Measure the voltage from the fourth stud of the five stud strip and to the white insulated ground stud. (See

figure #1 –V2) It should read more than 13.3 volts. If yes, continue to step 6. If no, check the in-line fuse from

the black insulated power stud to the fourth stud of the five stud strip. (See figure #1 – Arrow) If the fuse is

blown make sure the leads are not grounded and then replace the fuse.

6. The green LED lights on the control module should be illuminated. (See figure #1 – Circle) If yes, continue to

step 7. If no, ensure the nut on the third stud of the five stud strip and the white insulated ground studs are

tight. If they are both tight, the control module is defective and needs replaced.

7. Measure the voltage from the second stud (Ignition) on the five-stud strip to the white insulated ground

stud. (See figure #1 – V3) It should read more battery voltage. If yes continue to step #8. If no, ensure the nut

securing the wire on the second stud of the five stud strip is tight. If it is, the issue is the control module and it

needs to be replaced.

8. Measure the voltage from pin #1 on the four-pin connector to the white insulated stud. (See figure #2 – V4) It

should read the same voltage as at the front of the trailer... If yes, continue to step 8. If no, repair or replace

the wire from the black insulated stud to pin #1.
