Question about 2000 Ford Focus
Look at the wiring to the alt. if the is a single white wire going into the alt.,,, start the engine and have a partner wiggle the connector / wire and watch the lite. If the lite goes on and off with the wiggles ,,, change the wire connector. You may try cleaning with WD-40 or simular,but chances are the problem will be back.

You need to connect a meter across the battery terminals to determine whether the battery is being charged by the alternator. Compare the voltage at rest to that obtained when the engine is running. It should be about 12 volts at rest and then rise to approximately 14 volts. The voltage regulator (which controls how much voltage is being produced by the alternator and operates the charge lamp on the dashboard) on some vehicles is separate to the alternator. If the voltage is rising to within specifications as previously mentioned, the wiring to the lamp may be being earthed somewhere along it`s run to the alternator/regulator. Ian

Check for proper ground to body and engine, check for proper gauges on cables used.
