Thanks, Measure the bus voltage when your engine is running with minimal load (all electric stuff off) and rev the engine up a bit. It should not go much higher than 13.2 volts. If it does you may have a defective voltage regulator (part of the alternator). High bus voltage will cause excessive current through incandescant light bulbs and subsequently premature death. But they do burn nice and bright while they last,,, ;-) -- -Fred W Toys for sale, Hey get your toys here: <http://users.adelphia.net/~fredwills/>
