SB5 Smartbooster not working.

A slow flash on the status light of an SB5 is a short circuit.  Remove the two wires for the track but leave the power supply plugged in. If the light stops flashing, you have a short circuit in your wiring, or on the track, or in a locomotive.

If it still flashes with the track STILL unplugged,  then it can be the SB5 booster OR the P514 power supply. Unplug the P514 power supply from the booster. If the LED on the power supply STOPS flashing when you unplug it from the SB5 then the power supply is fine. This means the SB5 booster is damaged and needs to be sent in for repair.
