You need to check the DC voltage across the B+ and ground terminals. You also need to check the DC voltage across the remote and ground terminals. If the voltage is less than 11 volts, you need to check the B+ supply and remote wiring for breaks or open fuses. You should also check the ground connection to confirm that it's not loose.
If the voltage is OK, the output transistors are likely shorted.
