If Lamp Goes Out


If the lamps go out as the starter switch is closed, it indicates that there is a poor connection between the battery and starting motor. This poor connection will most often be found at the battery terminals. Correction is made by removing the cable clamps from the terminals, cleaning the terminals and clamps, replacing the clamps and tightening them securely. A coating of corrosion inhibitor (petroleum jelly will do) may be applied to the clamps and terminals to retard the formation of corrosion.
