I have a problem with my terex tb 60 all teh controls that work thru the superflex 4 controller dont work no lights on the sf4 light up , neither when I gave it a manual input but the relais board underneath it gives no power to the sf 4 we removed the cable break relais because the circuit was closed whe removed the circuit was still closed ? strange also the wire for the overload alarm was cut when reattached the buzzer goes and even the ground control doesnt work , engine shuts down when trying to operate is there an overload sensor somewhere ? has anyone electrical plans ? buy new or is it possible to repair ? or does someone has a used ground box for sale ?
check all of the ground circuits
