CHECKING THE TURN SIGNAL RELAY
1. Check:
● Turn signal light relay input voltages
Out of specification → Poor circuit connection
from main switch to turn signal light relay cou-
pler. Repair.

a. Connect the pocket tester (DC 20 V) to the
turn signal light and hazard relay coupler as
shown.
b. Turn the main switch “ON”.
c. Measure the input voltage of the turn signal
light and hazard relay.

2. Check:
● Turn signal light and hazard relay output volt-
age
Out of specification → Replace the turn sig-
nal light and hazard relay.

a. Touch probes of the pocket tester (DC 20 V)
to the turn signal light and hazard relay cou-
pler as shown.
b. Turn the main switch “ON”.
c. Measure the output voltage of the turn signal
light and hazard relay.
