[QUOTE="67panel, post: 632493, member: 13328"] You need to check battery voltage with engine running , should be between 13.8 and 14.2 volts . If not it most likely a dead alternator but could be a wiring fault , the WL wire shorting to earth. If you dont know the warning light works by having an ign live feed to one side of the bulb and voltage from the alternator on the other so when its charging the voltage is balanced on both sides and the bulb goes out.
