I was out yesterday evening and had a problem with the alternator and headlight switch - I think. Since I finished reassembling the 5 about two years ago, I have noticed that every time I turn on the headlight while the jeep is in motion it will miss one time as if for a split second all the power to the system had been lost. After that it runs fine and the lights work fine. Coming home last night, I switched on the lights and the alternator light came on and stayed on. The Alt light goes out when the lights are turned off. It's got a new HL switch and a fairly new alternator. Any thoughts on what the cause might be? A short or ground issue? Not sure where to start looking.
