Checking the power supply system (Taurus 1 and 2)

1. If something has happened to the power supply circuit, check the following connections:

a) the points of contact of the battery wires with the battery - make sure that they are clean and fit tightly.

b) the density of the electrolyte in the battery. If it is low, the battery must be charged.

c) Check the external wiring and connections of the generator.

d) inspect the drive belt, check its tension (see chapter 1).

d) check the tightness of the generator mounting bolts.

e) start the engine, check if the generator is making noise.

2. Using a voltmeter, check the battery voltage with the engine off. It should be approximately 12 volts.

3. Start the engine and measure the battery voltage again. It should now be 14-15 volts.

4. If the voltage values obtained during measurements are higher or lower than those specified in the specification, replace the voltage regulator. If replacing the voltage regulator does not help, then most likely the problem is in the generator.

5. Since special equipment is required to check and service the generator, a description of this procedure is beyond the scope of this publication. Generator maintenance is limited to checking the contacts and checking and replacing the brushes.

6. The ammeter (ALT) or alternator indicator light on the instrument panel shows whether there is a charge or not - current is flowing into or out of the battery. With the electrical equipment on and the engine idling, the ammeter may show no charge. At high idle speeds or normal driving speeds, the ammeter needle should remain on the side of the scale that shows the charge in the battery.

7. If the ammeter does not show a charge, or the generator light (if any) continues to light, then there is a problem with the system. Before checking the brushes or replacing the generator, check the condition of the battery itself, the tension of the belts, and the contacts of the electrical wires.
