- A) Check that the wire clamps are securely fastened to the battery terminals.
- b) Check Battery Status (see paragraph 3). If the battery is defective, replace it.
- V) Check battery wires and replace faulty ones.
- G) Check the condition of the wires and their connections going to the starter.
- d) Check that the starter mounting bolts are well tightened.
- e) Check the fuses in the box under the hood. If blown fuses are found. find out and eliminate the cause. Check the ignition switch (see chapter 12).
- and) Make sure the mode selector is in the PARK or NEUTRAL position (automatic transmission) or that you forgot to depress the clutch pedal (mechanical transmission). Check the correct operation of the transmission mode switch (automatic transmission) or serviceability of the starting circuit of the clutch (mechanical transmission). Checking and adjusting the automatic transmission mode switch is described in detail in Chapter 7. To check the clutch starting lever, refer to the electrical wiring diagrams at the end of Chapter 12.
- h) Check the operation of the start circuit interrupt relay. The relay is located in the fuse and relay box under the hood. Interrupt relay testing is described in chapter 12.
2. If the starter does not show signs of life when the key is turned to the START position, check if the battery voltage is being supplied to the starter relay. To do this, ask an assistant to turn the ignition key to the start position, and measure the voltage at terminal S yourself. A voltage approximately equal to the battery voltage should be applied to the terminal. If there is no voltage. check all circuits, fuses and relays associated with the starting system (refer to the wiring diagrams at the end of chapter 12 for troubleshooting). If there is voltage, but the starter does not work, remove it from the engine and check it on a workbench (see point 4).
3. If the starter turns but too slowly, measure the voltage at the motor leads while it is running and the current from the battery to the motor. This check must be performed on the engine. Rotate the starter for no more than 10 seconds. The voltage at this time should not fall below 9 V. If the voltage drops more, replace the starter. But before changing the starter, make sure that the battery is in good condition and charged, that its specifications match your car, that its wire contacts are securely tightened and not oxidized. At very low temperatures, the engine block may need to warm up to start.
4. If the starter is energized and does not run, remove the starter and have it checked on a workbench. Most likely. faulty traction relay. In some rare cases, the engine could jam - check this option by rotating the crankshaft by its pulley bolt. Fix the starter in a vise and connect the battery to it, as shown in fig. 14.4. Turn on the starter for no more than 10 seconds. The armature of the traction relay should extend the lever with the gear and freewheel, and the gear should begin to rotate. If the gear extends, but does not rotate, then the motor is faulty. If the relay clicks, but the lever with the gear does not extend, then either the relay or the motor is faulty. If the gear extends and rotates, then the starter is good.
