Looking for some help with my TIU. I typically only run trains during the holiday season. Today I pulled out my temporary layout and fired up my RK PRR L-1. Stated up just fine and ran a few inches until a spark at a switch which tripped the TIU circuit breaker. Replaced the circuit breaker and plugged everything back in with no train on the track. Immediately a spark and the breaker blew again. I tried once more, this time with the TIU not connected to the track. Same problem. Apparently the "Fixed Voltage IN1" circuit in the TIU has a short. I can apply power to the "Fixed Voltage IN2" terminals with no problem. The output voltage from the Fixed (DCS) Out2 terminals checked fine.
Has anyone had a problem like this before? is there an easy fix? since the IN2 and OUT2 terminals seem to work fine, can I just use those? If so, how do I set up the TIU to use the IN/OUT2 circuit instead of IN/OUT1? Thanks much for any help.
