Starters: Diagnosis Hyundai Sonata IV рестайлинг

STARTER RELAY TEST

1. Check continuity between relay terminals No. 85 and 86, and between terminals No. 30 and 87. (Scheme 1) Continuity should exist between terminals No. 85 and 86. Continuity should not exist between terminals No. 30 and 87. If continuity is as specified, go to next step. If continuity is not as specified, replace starter relay.
2. Apply battery voltage and ground between terminals No. 85 and 86. Continuity should now exist between terminals No. 30 and 87. If continuity is not as specified, replace starter relay. If continuity is as specified, starter relay is okay at this time.

Scheme 1

IGNITION LOCK (CLUTCH PEDAL) SWITCH TEST - M/T

Disconnect clutch pedal switch connector, located on pedal assembly bracket. Using ohmmeter, check continuity between switch terminals. Continuity should exist with switch depressed. Continuity should not exist with switch released. If continuity is not as specified, replace clutch pedal switch. (Scheme 2)

Scheme 2

ARMATURE TEST

1. To check armature for a grounded circuit, check continuity between commutator and armature coil core. (Scheme 3) No continuity should exist. Replace armature if continuity exists.
2. To check for an open circuit, check continuity between individual brush segments at commutator end of armature. (Scheme 3) Continuity should exist between each individual brush segment. Replace armature if no continuity exists on any brush segment.
3. Support armature in "V" blocks, with "V" block positioned at each bearing end of armature. Using a dial indicator, check armature runout at center of commutator and at end of armature. Replace armature if armature runout exceeds specification. See «STARTER SPECIFICATIONS»(ref-169257-S00666859292004120400000).
4. Using caliper, measure commutator outside diameter at center of commutator. (Scheme 4) Replace armature if commutator outside diameter is not within specification. See «STARTER SPECIFICATIONS»(ref-169257-S00666859292004120400000).
5. Measure insulator depth between commutator segments. (Scheme 5) Replace armature if insulator depth is not within specification.

NO-LOAD TEST

1. Place starter in soft-jaw vise. Rotate carbon pile rheostat to OFF position.
2. Connect fully charged 12-volt battery, switch, voltmeter (15-volt scale), ammeter (100-amp scale), and carbon pile rheostat as shown. (Scheme 6) Adjust carbon pile rheostat until voltmeter indicates 11.0-11.5 volts.
3. Connect remote starter switch between solenoid terminals "B" and "S". Activate remote switch (maximum 10 seconds), and note reading on ammeter. Ensure starter rotates smoothly and maximum amperage draw is 90-amps at a minimum speed of 3000 RPM. If starter does not test as specified, replace starter.

Scheme 6

Return Test

Disconnect field coil wire from terminal "M" of solenoid. Apply battery voltage to terminal "M" of solenoid, and ground starter case. Manually pull out pinion drive, and then release it. (Scheme 7) Pinion drive should return quickly to original position. If pinion drive does not return to original position, replace solenoid.
