Flashing lights after a short
Having got my N scale layout up and running with a Lenz Set 100 in control, if I get a short then any loco fitted with a Lenz mini-gold decoder (via a NEM651 socket) sits there with the lights flashing once the short is reset. The locos with TCS M1s don't seem bothered! I cannot find a simple way of resetting them but assume there must be one. If I lift the loco off the track and replace it, it's fine but not ideal to say the least.
Anyone able to give me a simple pointer as to what is happening here please and a better way of resolving the reset?

One thing to remember , The Control/Power station may regulate the voltage from your Power supply (or transformer in older terminology) But it is better to have a power supply that supplies very close to the required track voltage.
the reason for this is that any voltage regulation (or lowering from 16v down to 12v) uses energy , which is dissipated as heat . Consequentially that will lower the amount of current that you can utilize on your track.

What I should have said is:
The greater the input voltage , the more regulation required and the less current available to the track
The closer the input voltage is to the track voltage - the maximum current is available to the track
I hope thats a bit clearer

Hi Andrew
Yes ,I think 99% of the time it wouldn't make any difference.
Most systems have overcurrent protection of some sort
Lenz use thermal overload detection
This is from 1 of there manuals
1. The fast acting current limiting circuit designed to very quickly
shut down the LV101 track output if a short is detected. This
circuit activates at over 5 Amps.
2. Thermal overload protection. The LV101 has a long term
thermal overload circuit designed to shut down if its temperature
exceeds its rated capacity or value.
How does this translate to the output power you can expect?
For short term loads such as locomotive start up or slow speed
operation the LV101 can deliver over 5 amps of DCC track power.
For long term loads, the LV101 can continuously deliver between
4 and 5 Amps at the DCC-voltage you set as long as the
difference between input and output voltage is low enough to
prevent the LV101 from prematurely overheating. Otherwise the
thermal overload protection will limit the power output and shut
down the LV101.
That means you can achieve significantly more track current for
running trains with a power supply that matches best to the
LV101s potential.
I hope that clarifies
