I need some help on my UP H-7, cat# 6-11399
I repaired the smoke unit. The cab light would flash when I attempted to use the smoke feature. The smoke unit now works and the there is no cab light blinking. The engine runs fine (forward/backward, lights, smoke), but no communications with the tender.
After the smoke unit repair, the engine would no longer communicate with the tender. The tender works fine with other legacy engines. I tested the IR transmitter and it appears to be OK. I used the diode tester on my meter. I also checked the wiring to and from the IR transmitter. The wiring checks fine with continuity.
I am wondering if somehow I damaged the RCMC?
I looked for a reset code, but I could not find one. Does anyone know if there is a factory reset code for this early (2012) Legacy engine?
I did re-program the engine ID in case that would reset the RCMC, but still no change.
Is there any other way to see if the IR transmitter is good or if the RCMC has failed?
Any thoughts as to what else I should try?
