reading is about 12 V, the reserve lighting device is
defective. When the reading is 0 V, the main switch,

Trouble (b): Both filaments for upper beam and lower
beam are turned on at the same time.

Trouble (c): The high beam is not dimmed when the
low beam burns out and the high one is

TURN SIGNAL CIRCUIT AND AUTOMATIC
Turn Signal Circuit
A wiring diagram of the turn signal circuit is shown
When the ignition switch is on and the
turn signal switch is turned to
a ground is
provided for the circuit so current can
to the right or left turn signals flows through the closed
contacts and through the resistance wire inside the turn
signal relay, and the turn signals go on. The resistance
wire quickly heats up, expands, and allows a spring to
pull the contacts open. When the contacts have opened,
the circuit is broken, the turn signals go off, and the
resistance wire cools and contacts, closing the contacts
so that the cycle can begin again. The indicator light
for the turn signals indicates that
