ceptacle to the key sw itch and try
to start the engine w ith the key. If
it starts, you have corrected the
problem . If it doesn’t start, pro­
ceed to the follow ing steps.

(c) Test each of the tw o red w ires
for continuity by placing the
ends of the continuity tester
w ires at both ends of a single
w ire (see Figure 6-70). If the
lam p lights, electricity is flow ­
ing through the w ire and it is
okay. R epeat this step for the
other red w ire. Let us know if a
w ire doesn’t light the bulb.
(d) A fter testing both red w ires,
reconnect the negative (-)
battery cable to the grounding
screw on the battery bracket.
G . If the red w ires in the w iring
harness are okay, you m ay have
either a faulty keysw itch or a bad
