the connectors for proper installation. The check-
ing procedures below may be used to check the
operation of a switch or motor after the cause of
the electrical failure has been isolated to a par-
ticular part of the circuit. Refer to the circuit
diagrams. See Figures 16-58, 16-59 and 16-60.
Turn ignition switch on and with test light
check output terminal of relay. If tester does
not light, the relay is inoperative or there is
a short or open circuit between ignition switch
and relay assembly.
(Check fuse at dash
panel.)
a. Checking Feed Circuit Continuity
at Circuit Breaker
1. Connect one test light lead to battery side of
circuit breaker and ground other lead. If tester
does not light, there is an open or short circuit
in feed circuit to breaker.
2. To check circuit breaker disconnect the output
feed wire (the wire opposite the power source
feed to the breaker) from the breaker. Connect
one test light lead to the output terminal and
ground other lead. If tester does not light,
circuit breaker is inoperative.
b. Checking Relay Assembly at Shroud—
Oldsmobile " A " & Chevrolet " B " Styles
1. With test light check relay feed. If tester does
not light, there is an open or short circuit be-
tween relay and circuit breaker.
c. Checking Feed Circuit Continuity at
Control Switch on Instrument Panel
1. Disengage harness connector from switch.
Connect one test light lead to feed terminal of
switch connector and ground other test lead to
body metal. If tester does not light, there is an
open or short circuit between switch and power
source.
d. Checking Control Switch at
Instrument Panel
1. Disengage harness connector from switch.
2. Use a #12 gauge jumper wire and insert one
end into the feed terminal and the other end
into one of the other terminals. Tail gate
window motor should operate.
