Are they clicking in time with the booster and brain shutting down?
If
so, then it's not the auto reversers.

None? Hmm... Well, it's possible you have the beeps turned off. Or,
it could be that the short or whatever is too quick for the beeps.
Just thought of something...what kind of load are we talking about
here
with the locos? Are there a lot of sound locos on the track?

FYI: On my club layout, the screws actually were loose on a couple of
our boosters with that wire. I was able to tighten them a full turn, and
some of our erratic operation went away after that.

Ick. If you're running a club layout, you better rewire that or it'll
drive you nuts. At my club, we have one DCS100 & 8 DB200's. One of the
DB200's powers a freight yard, and another powers all our stationary
decodered switch machines. The other 6 power the mainline.
Each mainline booster powers 1 or 2 power distribution/detection
panels
scattered throughout the layout. Each panel has 4 circuit breakers from
Tony's. Each of these breakers powers 1/4th of a BDL168 block detector
(which detects up to 16 blocks in four zones). The BDL168's 16 outputs go
out to the track bus for each block.
On our layout, if there's a short, it only effects 4 blocks (unless
it's
at a boundry...then the booster trips and knocks out a large chunk o'
layout). Each mainline block is about 15 feet, BTW.
IMHO, you really should get some circuit breakers and divide up your
club's layout. Maybe not as much as we did, but still...ick.
