What is wrong when a battery will not hold charge when driving causing lose of lights and power?
If the battery is less than 4 or 5 years old. the most likely reason's are 1- The alternator not working at all. 2 - the belt to the alternator broke. 3 - cables at the battery are corroded. 4 - the battery can be almost completely dead.
To check alternator. Get a jump from someone, if car starts, check the voltage at battery terminals. It should read approximately 15 volts. with all connections and belts OK. If it reads below, say 13 volts, then alternator or voltage regulator is no good. If it starts with a jump, and alternator reads OK ,then let engine run for about 15 minutes. stop engine and check voltage across terminals, it should be 12.5 volts. IF below 12.4 volts, replace battery, but first do a battery drain test. Disconnect negative battery terminal, with all accessories off, connect a test light to battery clamp and negative post, if light comes on, there is a short, discharging the battery.
