I recently re-inserted the batteries in my Cab-2 after removing them while working on scenery for a few months. Now, everything turns on, but I can't get power to the track in Command Mode. Everything works OK in Conventional Mode. Command Mode was working fine previously.
My system has PH-180s feeding TPC 400s, and the voltage reads 18V at the connection in to the TPCs. But, the output from the TPCs reads a low 1.4 Volts and will not change after turning on track power with the Boost button and rotating the Red Knob. Readings on the Cab-2 display appear normal, like they did before the batteries were removed. The Cab-2 remote connection to the Command Base appears OK (Channel 3) and the Train LEDs on the TPCs blink. I have checked all connections, and they appear tight. I have not added anything to the wiring in the interim. And, yes, I checked the three batteries, and they all read a full 1.5V.
Any suggestions?
