I have the PRR TMCC crane. I keep the crane on a parked siding with power. Last night I noticed that one of the front LEDs was on. I normally keep the LEDs off when I am not using the crane. When I went to toggle the front LEDs using my Legacy remote, the left LED turned off and then the right one turned on. It would seem the logic circuit has become reversed for the one LED. The rear LED works fine. I tested all the other functions of the crane and they all worked correctly.
For grins, I reprogrammed the ID in the crane. No luck. I checked the book and there is no programming number for the crane listed. It only states how to program the ID. Normally, you can reprogram an engine by entering its ID number then the code feature number. Not sure how I can get the crane to have the front lights in sync. The circuit is working because it does toggle the LED. Its just out of sync with the other LED.
