6. Measure the voltage between the relay coil (by back probing) and the dual pole receptacle ground. (See figure

#3 – V8) It should measure the same as tractor battery voltage. If yes, continue to step 7. If no, replace or

repair the wire from the aux pin to the relay.

7. Measure the voltage between the green LED connector (relay side) and the dual pole receptacle ground. (See

figure #3 – V9) It should measure more than 13.3 volts. If yes, continue to step 8. If no, the wire from the

relay coil to the connector is the issue. Repair or replace the wire.

8. Measure the voltage between the relay input contact (by back probing) and the dual pole receptacle ground.

(See figure #3 – V10) It should measure same as the tractor battery voltage. If yes, continue to step 9. If no,

the issue is in the blue wire and in-line fuse from the seven-way aux pin to the relay input. Repair or replace

this wire.

9. Measure the voltage between the relay coil (yellow wire is connected) and the dual pole receptacle ground.

(See figure #4 – V11) It should measure battery voltage, then dropping to zero volts in less than a minute. If

yes, continue to step 10. If no voltage is measured, the coil of the relay is bad, replace. If voltage is measured

but never drops, skip to step 12.

10. Measure the voltage between the dual pole receptacle positive and the dual pole receptacle ground. (See

figure #4 – V12) It should measure more than 13.3 volts. If yes, skip to step 12. If no, continue to step 11.

11. Measure the voltage between the relay output (30 terminal) and the dual pole receptacle ground. (See figure

#4 – V13) It should measure more than 13.3 volts. If yes, the issue is in the wire between the relay output (30

terminal) and the positive post of the dual pole receptacle, repair or replace. If no, try a known good relay. If

you now have voltage, the issue was the relay. If still no, install the original relay and continue to step 12.

12. Move to the liftgate battery box to continue troubleshooting.
