I've been using the optical sensors on my B' K-27 to feed the chuff trigger on my Phoenix P5 successfully for 6 months, however, the sensors seems to have quit. I say seems because I'm not 100% sure that is the problem.
I swapped out the P5 with another and it doesn't chuff either. I verified the wires are still connected up properly to the circuit board in the tender. Everything on the sound card works but not the chuff. I hooked up a reed switch and magnet in place of the sensor jumpers and the chuff works.
So it seems that either the optical sensors have failed or a wire or circuit within the loco or tender has failed. The diagram shows 2 sensors and it seems unlikely they would both go out at the same time so it's probably something in the circuitry? If one sensor failed would it cause the other to fail also?
The problem occurred Sunday when I put the loco on the tracks and started it up. I run DCC. The loco started moving and the chuff was working, then the loco kind of sputtered, lurking forward, stopping and then forward again. At first I thought it was my power connection to the rail, but then discovered one of the big plugs between the loco and tender wasn't pushed in all the way. After I pushed in in tighter the loco ran fine but no more chuff.
Has anyone else had this issue?
