HiCustomer


Here is how to replace the starter in your Suzuki Swift 1995:


REMOVAL & INSTALLATION







Fig. 1: Starter motor assembly



  1. Disconnect the negative battery cable.
  2. Raise and support the vehicle safely.
  3. Label and disconnect the starter solenoid electrical connector.
  4. Remove the mounting bolts from the starter motor, then carefully lower the assembly from the vehicle.

    To install:


  5. Install the starter motor assembly complete with any shims that may be used between the engine block and the starter.
  6. Install and tighten the starter mounting bolts to 17 ft. lbs.. (23 Nm).
  7. Connect the starter solenoid electrical connector.
  8. Lower the vehicle and connect the negative battery cable.

But before you go into that, you may want to test a few things out...:


TESTING



  1. Connect a voltmeter in conjunction with an inductive amp probe to the battery.
  2. Disable the ignition system.
  3. Set the vehicle in park or neutral and set the parking brake.
  4. Turn the key to the START position and read the meters.
  5. If the voltage reads 12 volts or greater and the amperage reads 0–10 amps, further testing to the solenoid and relays are applicable.
  6. If the voltage reads 7.5 and above with the amperage readings above 150 amps, move onto the testing of feed circuit resistance to establish a properly functioning starter circuit.

Feed Circuit Resistance


  1. Connect a voltmeter to the negative battery post and the negative battery cable clamp.
  2. Turn the key to the START position and read the meter.
  3. If any voltage is recorded, Clean the contact area of the two items.
  4. Do the same test for the positive battery terminal post and clamp.
  5. If any voltage is recorded, Clean the contact area of the two items.
  6. Connect to the negative battery terminal and the engine block near the ground cable.
  7. Turn the key and take reading.
  8. If the reading is above 0.3 volts, clean up the contact area.
  9. If this does not correct the high reading, replace the cable.
  10. Connect to the positive battery terminal and the terminal on the starter solenoid.
  11. Turn key and take reading.
  12. If the reading is above 0.3 volts, clean up the contact area.
  13. If this does not correct the high reading, replace the cable.
  14. If necessary, move onto solenoid testing.

Starter Solenoid


  1. Connect the voltmeter to the Solenoid terminal to ground.
  2. Turn the key to START.
  3. If battery voltage is not found, check the ignition switch circuit.
  4. If battery voltage is found, proceed by connecting an ohmmeter to the battery and the ground terminal of the solenoid.
  5. Turn the key and take reading.
  6. The ohmmeter should read zero, if not repair ground connection.
  7. If these tests are performed and the solenoid still does not energize, replace the solenoid.

And if it's not the starter, and the solenoid or relay... here's how to replace that:
