Thanks guys. I will do a voltage drop on the neg and pos sides. The HID system has been in the car for the last 7 years with no problem. It was only when I swapped out one of the bulbs that all this started. As for the 100 amp alt., It has been in the car with no problems since 2005. The wiring was replaced when I installed the E-Codes and went to a higher wattage bulb until I got the HIDs. All wires are 12 gauge with relays for the high and low sides. The famous factory headlight relay is bypassed. The factory bight light relay is still in use. And its the speedo thats jumping up and down. The tach is dead. I checked the voltage to D+ and had voltage there so I know it is activating the field. The Batt terminal also had 12 volts (12.76) As for the volt meter I really do not remember where it is connected. I did that when I first got the car in 2000. Being over 70 now, my memory seems to be wondering. Mostly wondering where it is and why I can't find it. I exchanged the Bosh alt today for a new one so as soon as it stops snowing and the weather gets above freezing I will swap it out. The only good thing that came out of this is that I discovered that the bottom mounting bolt had sheared off at the block and I now have to drill it out and replace it with a higher grade bolt. I will let you know what I find in a day or two. Thanks again for the suggestions. P.S. Art I hope you are doing well, I haven't talked to you in several years.
