If you suspect a defect in your charging system, first perform these general
checks before going on to more specific tests.
- Check the condition of the alternator belt and tighten if necessary.
- Clean the battery cable connections at the battery. Make sure the connections
between the battery wires and the battery clamps are good. Reconnect the negative
terminal only and proceed to the next step.
- With the key OFF, insert a test light between the positive terminal
on the battery terminal clamp. If the test light comes on, there is a short
in the electrical system of the vehicle. The short must be repaired before
proceeding. If the light does not come on, then proceed to the next step.
NOTE: If the vehicle is equipped with an electric clock,
the clock must be disconnected.
- Check the charging system wiring for any obvious breaks or shorts.
- Check the battery to make sure it is fully charged and in good condition.
