Ph-Pro Power Pro 5 amp connections and status lights

The left side of the box is the 5 amp booster side. It has a 4-pin connector. The first set of two pins is for incoming AC power. Typically, this is 15 volts AC / 5 amps from the 120 VAC transformer. The second set of two pins is the track output, which should also measure about 15 volts AC. Notice the small 4-wire jumper on the control bus jack, which goes to the other side of the box. See below. The status light should be a solid red. A slow flash indicates a track short. A fast flash indicates the control bus signal is not present.

Here, we see the right side of the box. This is the command station side. The other end of the control bus cable goes here, and you also have the connection jack for the Cab Bus. Notice the 2-wire track output for a programming track. The track light is usually solid yellow except when in service mode programming /programming track mode. In Service mode, the left side running the layout shuts off, and the right side with the programming track output is now active.

================================================

A short circuit is a slow flash on the left side for the track power output. Remove the two wires for the track power output only, leaving the input power connected. See if the status light changes to solid. If it does change to solid, the box is not damaged, but you have a short circuit elsewhere.

If the light does NOT change with the track unplugged, the box is damaged and must be sent in for service.

Please send it in for service. No RMA number is needed for repairs.
