Lights
dim?
- Bad connection:
Check all transformer and light fixture connections.
Low voltage cable should be fastened tightly to the
transformer.
- Overloaded line:
Disconnect one or more of the bulbs to see if the other
lights become bright again. If they do, remove one of
the fixtures, use a more powerful transformer or split the
cable run and add a second transformer.
- Lights are dim at
the end of the cable: On a long run of cable, the
lights farthest away from the transformer may become too dim
due to excessive voltage drop. When this occurs,
change to a heavier gauge of wire or use a different wiring
layout. If the cable run is within specified limits,
check for a short circuit.
- Circuit breaker
trips when transformer is turned on: Disconnect
the transformer from the AC outlet, and disconnect the low
voltage cable from the transformer. Reset the circuit
breaker (or replace a blown fuse), plug in the transformer
and turn it on. If the fuse or circuit breaker doesn't
blow, the transformer works. If it trips the circuit
breaker again, return the transformer to your
dealer.
- One lamp won't
light: Check the cable connection. If the
lamp still won't light, test the socket with a lamp that does
work. If it doesn't work with a new bulb, you may have
a faulty socket.

Lights
out?
- Overloaded transformer: If
lights initially turn on but then shut off, this indicated
that the transformer is either overloaded or shorted.
Check the connections at the transformer and the
fixtures. If you are using loop or double-leg wiring
layouts, be careful to connect the positive and negative wires
to the proper terminals on the transformer.
- Transformer power is off:
Check the on/off switch and/or the circuit breaker to verify
that the outlet is activated. to test a
photo-controlled power pack, place a piece of dark tape over
the photoelectric eye to return the power pack on. If
the power pack is defective, contact your manufacturer.
- Break in cable: Manually
inspect the entire cable run for any cable breaks that could
be causing shorts.
