correct multimeter readings.
Step 1.
Open lower center instrument panel (page 2-424). Pull lamp socket (1) out of right turn signal
indicator (2). Push in lamp (3), turn counterclockwise and pull out. Using multimeter set to 20 vdc
scale, connect red test lead to center contact (4) and black test lead to ground. Move turn signal
switch (5) to right turn position and check for 11 to 13 vdc on multimeter. Move turn signal switch
(5) to neutral position. Disconnect test leads.
a. If multimeter reads 11 to 13 vdc, go to step 3.
b. If multimeter does not read 11 to 13 vdc, go to step 2.
Step 2.
Using multimeter set to 20 vdc scale, connect red test lead to 57A wire (6) in connector (7) and
black test lead to ground. Move turn signal switch (5) to right turn position and check for 11 to 13
vdc on multimeter. Move turn signal switch (5) to neutral position. Disconnect test leads.
a. If multimeter does not read 11 to 13 vdc, put lamp (3) into lamp socket (1). Push in,
