• Completely remove the power wire from both motor connections. Attach 6 gage or larger jumper cables from a 12 volt battery source to the motor connections. Does the motor operate in one direction with normal power and with no grinding noise etc.?  Change the jumpers to the opposite connections, does the motor run correctly in the opposite direction? Motor is good.
     
  • If not bring motor into us and we will send it in to the manufacture for a repair estimate, warranty, or you may purchase a new replacement motor. Both locations have rental motors to use while yours is in for repair. $3.00 a day for the standard motor $6.00 a day for the Super Duty rental.
     
  • Run/ check the wiring from the battery box to the motor and to the switch. Look for kinks, worn insulation, burnt marks etc. indicating that the wire may be grounding out and splice and repair or replace as required. Ensure you check and inspect carefully the area where wire penetrates the dump box or frame/ bed rail and at the rear pivot point of the frame where the bed pivots. Check and lightly tug on all connections and terminals to ensure the wire is still crimped and making good contact. Ensure all contacts are clean and making metal to metal contact and remove all corrosion.
     
  • Check the breaker (40 amp, 50 amp or 90 amp, depending on tarp system) in the battery box (on the positive wire) to ensure it is still good and working properly. A trick I learned was to remove the rectangle copper colored breaker (BUS style auto reset breaker) from the wiring in battery box and shake it up and down or back and forth vigorously, if you here nothing rattling inside it the breaker is good, if you hear rattling  inside the breaker replace it. Old Aero systems also had a second (40 amp) breaker just off the positive motor lead, don’t forget to check that one too.  You will find these BUS auto reset breakers (resets in about 6 seconds) with the Aero, Mountain Tarp systems and the old Rotary switch style RollRite Tarp systems. These breakers are also used with the Rocker Switch and the Mechanical Reversing DC relays in the Aero and Mountain Tarp Systems. For RollRite rocker switch systems they use a mechanical Marine (35 amp) outdoor breaker with a yellow reset flipper in or around the battery box on the positive wire.
     
  • Be sure to check the operation of the tarp system to ensure that your tarp is not jammed/ wedged into the winder bar, that the arms are not rubbing down the side or getting caught on something which will also cause the breaker to trip.
     
  • No matter which switch setup (Rotary or Rocker switch) you are using it is advised that you do not, when opening the tarp, let the tarp system pop the breaker with the top bow forced against the wind deflector housing, to verify the system is opened. Switch should be released when the top Tarp Bow just touches the wind deflector housing, not when the breaker pops, or when you visually see the arms forward and the top tarp bar against the housing. Continuously operating the system this way will burn up the switch, breakers and reversing relays.
