Welcome to the board.
You need to take a voltage reading at the battery when the engine is running; an incorrectly adjusted or faulty voltage regulator will cause an over-volt condition which will burn out lamps. The standard charging voltage for a 6-volt system is 7.2 volts but the lamps will usually tolerate up to 8 volts. |
