Thunder 7000 Tarp System Troubleshooting Guide
Below you will find troubleshooting steps for common tarp system issues


Remote function not working.

1. Reset system by removing trailer power connection for 15 seconds then reconnect.
2. Turn on the tarp system by pressing the (Open) & (Close) buttons simultaneously on the keypad for 3-5
seconds until the LED and buttons illuminate.
3. Test remote function.
4. If no function, reset system power and reprogram remote per the remote programming instructions.
5. If remote function now works, this can be an indication that the trailer power connection is loose and
needs reworked and tightened.
6. If still no remote function, check battery level indicated by a continuously flashing status LED on the
remote when the flip lid is opened indicating less than 25% charge, replace if needed.
7. Replacement of keypad or remote may be necessary if above steps fail to work.


Tarp system will not power on.

1. Make sure that the 2-pole power cord is plugged into the trailer and has the proper polarity and voltage
to the tarp system. Vertical plugs are + positive on top, horizontal plugs are + positive to roadside.
2. Check that the tarp system circuit breaker, near the tractor battery, is allowing power through by using a
voltmeter or test light. Replace if necessary.
3. Turn on tarp system by pressing the (Open) & (Close) buttons simultaneously on the keypad controller
for 3-5 seconds until the LED and buttons illuminate.
4. Test the remote functions of the tarp system by pressing the (Open) & (Close) buttons simultaneously
on the remote 3-5 seconds to verify keypad button failure.
5. Check for grease, dirt, and corroded connections at the battery terminals, circuit breaker and also at
the trailer power receptacle plug and outlet.
6. Check for proper voltage (12v-14v) on the back side of the 2-pole trailer receptacle. Also check for corrosion
and looseness.
7. Check for proper connection of the communication cable between the inner control box and the keypad
controller.
8. Unplug the trailer power from the 2-pole receptacle, wait 15 seconds, re-plug power and verify operation.
9. If the status LED illuminates green briefly on the keypad controller after plugging in power but does not turn
on when pressing the (Open) & (Close) buttons simultaneously, then this indicates the keypad controller has
failed and needs to be replaced.
