Starting System: Overview Mazda Tribute I рестайлинг

The starting system consists of the

1. starter motor
2. starter motor relay
3. transaxle range (TR) sensor (automatic transaxle)
4. clutch pedal position (CPP) switch (manual transaxle)
5. battery
6. ignition switch

When the starter solenoid is energized, a magnetic field is created in the starter solenoid windings. The iron plunger core is drawn into the starter solenoid coil, and a drive lever and pin connected to the starter drive engages the drive pinion gear to the flywheel ring gear. When the plunger is pulled all the way in, its contact disc closes the circuit between the battery and the motor feed terminals. This sends current to the motor, and the drive pinion gear cranks the flywheel to start the engine.

When current flows to the starter motor, the starter solenoid pull-in coil is bypassed, and the hold-in coil keeps the drive pinion gear engaged with the flywheel until the ignition switch is released from the START position.

An overrunning clutch in the starter drive protects the starter motor from excessive speeds during the brief period before the driver releases the ignition switch from the START position as the engine starts.

Vehicles equipped with a manual transaxle have a clutch pedal position (CPP) switch mounted on the clutch pedal bracket. The CPP switch prevents operation of the starter motor unless the clutch is fully depressed.

Vehicles equipped with an automatic transaxle have a transaxle range (TR) sensor mounted on the transaxle. The TR sensor prevents operation of the starter motor unless NEUTRAL or PARK is selected.

1. Remove the starter motor. See «STARTER MOTOR - 2.3L»(ref-221838-S13182704932006022600000) or «STARTER MOTOR - 3.0L (4V)»(ref-221838-S36603467702006022600000) .
2. Check the wear patterns on the starter drive gear and the flywheel ring gear. If the wear pattern is normal, install the starter motor. See «STARTER MOTOR - 2.3L»(ref-221838-S13182704932006022600000) or «STARTER MOTOR - 3.0L (4V)»(ref-221838-S36603467702006022600000) .
3. If the starter drive gear and the flywheel ring gear are not fully meshing and both of the gears are scored or damaged, install a new starter motor. See «STARTER MOTOR - 2.3L»(ref-221838-S13182704932006022600000) or «STARTER MOTOR - 3.0L (4V)»(ref-221838-S36603467702006022600000) . If necessary, install a new flywheel/flexplate. For 2.3L see «FLEX PLATE OR FLYWHEEL AND CRANKSHAFT REAR SEAL»(ref-221816-S10098536492006022600000) . For 3.0L (4V) See «FLEXPLATE»(ref-221817-S05623297702006022600000) .
