I completed and ERR install (commander and GS4 sound unit) in an older Williams brass Daylight. Everything went well. It ran the layout for about 2 days. Last night I needed to move it to a siding. It ran about 20 feet on a straight away, stalled, ran a few feet more then stopped cold. The Z4000 went red on a short. I thought it might have been one of the passenger cars is was pulling.
I pulled each car, still in shorted.
I pulled the loco, not shorted (so not a track issue).
I pulled the tether from between the loco and placed only the loco on the tracks. Headlight came on and No short.
I placed the tender only on the tracks. No short
I placed them both on the tracks and reconnected the. The short returned.
I pulled the tender shell. Still shorted.
I pulled the sound board only. Still shorted.
Seems like I have an issue within the commander board... if so, WHY?
Other than providing additional cuss words that I may not have covered last evening, Any ideas here???
