DCC Short detection - 4
6
6: At this point we discover that the short circuit current
is flowing in the branch feeder. Even in cramped spaces,
it is easy to follow the short circuit current without
disconnecting any wiring.
Summary
Wire a #1156 lamp in series with each booster output wire to
limit current and prevent the booster from tripping while testing
a short circuit. Wire a DPDT switch to switch from normal opera-
tion to the #1156 lamps for testing when a short circuit occurs.
Use a clamp-on ammeter to detect current flowing in one track
bus or feeder wire to isolate a short circuit.
