DRIVE BELT
ON−VEHICLE INSPECTION
1. INSPECT DRIVE BELT’S INSTALLATION CONDITION
Check that drive belt fits properly in the ribbed groves.
2. INSPECT DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
DENSO BTG −20 (95506−00020) or
Borroughs No. BT −33−73F
Drive belt tension:
New belt 100−150 lbf
Used belt 60−100 lbf
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been on a running
engine for 5 minutes or more.
After installing the drive belt, check that it fits properly in
the ribbed grooves.

4. INSPECT VOLTMETER
ON−VEHICLE:
Compare the tester and voltmeter indications.
If error is excessive, replace the voltemeter.
5. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, and check that the receiver gauge needle indicates EMPTY.
(c) Connect terminals 4 and 5 on the wire harness side con- nector through a 3.4 W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights up and the receiver gauge needle moves towards the full
side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
6. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Between terminalsResistance (Ω )
A − B85.5 − 105.5
A − C126 − 150
B − C*90 − 11 0
*: Include voltmeter resistance
If resistance value is not as specified, replace the fuel receiver
gauge.

BODY ELECTRICAL DEFOGGER SYSTEM

(f) The point where the voltmeter deflects from zero to sever-
al V is the place where the heat wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but gradually increases to about
12 V as the meter probe is moved to the other end.
4. IF NECESSARY, REPAIR DEFOGGER WIRE
(a) Clean the broken wire tips with a grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire to be
repaired.
(c) Thoroughly mix the repair agent (Dupont paste No. 4817
or equivalent).
(d) Using a fine tip brush, apply a small amount to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.

ON−VEHICLE INSPECTION
1. INSPECT BATTERY POSITIVE VOLTAGE
Battery positive voltage: 10 − 14 V
2. DISCONNECT CONNECTORS
(a) Disconnect the connector from the actuator.
(b) Remove the control relay from the actuator bracket.
(c) Disconnect the 2 connectors from the control relay.
3. CONNECT ACTUATOR CHECKER (SST) TO ACTUA-
TOR
(a) Connect the actuator checker (SST) to the actuator, con-
trol relay and body side wire harness through the sub −
wire harness C (SST) and E (SST), as shown.
SST 09990−00150, 09990 −00200, 09990−00210
(b) Connect the red cable of the checker to the battery posi- tive (+) terminal and black cable to the negative ( −) termi-
nal. Connect the black cable of the sub −wire harness to
the battery negative (−) terminal or body ground.
