I've isolated a new section that showed a short. I can probably find that easily.
However, the old layout now mystifies me. It too still shows a short when tested with a 9V battery and either a buzzer or LED, but my Zephyr throttle shows no short and now runs locos fine.
Is it possible the short is rather weak and while a 9V battery will buzz loudly, the Zephyr will ignore it? I double checked and have no rolling stock on the layout anywhere. Or is the DC battery juice significantly different than the juice put out to the track by the DCC throttle?
Previously the 9v test worked normally all over. No alarm until something placed across the tracks.
COuld be a weak short, through a resistence, not liek two wires twisted together. If it doesn;t draw 2.5 amps (or 3 amps if you have an Xtra), it won;t trip.
Does the Zephyr trip if you set a quarter on the track at all places?
It could be one feeder backwards, if not soldered or otherwise securely attached.
