TION METER AND IGNITION SWITCH
CONNECTOR.
1) Turn ignition switch to ON.
2) Measure voltage between combination meter connector
and chassis ground.
: Connector & terminal
(i14) No. 11 (+)—Chassis ground ():
Is voltage more than 10 V?
: Go to next.
: Check the following and repair if necessary.

Blown out fuse (No. 15).
NOTE:
If replaced fuse (No. 15) blows easily, check the harness
for short circuit of harness between fuse (No. 15) and com-
bination meter connector.

Open or short circuit in harness between fuse (No. 15)
and combination meter connector

Open or short circuit in harness between fuse (No. 15)
and ignition switch connector

Poor contact in ignition switch connector
: Is there poor contact in combination meter
connector?
: Repair poor contact in combination meter connec-
tor.
: Replace bulb or combination meter.
