What are you using to measure the voltage? Do not rely on the Volt meter on the dash. It sounds as if your alternator is about to go. As the car is running, open the engine compartment and listen for any noises coming from the alternator. If you hear any type of a whistling sound coming from it (or any other strange noise) I would suspect the alternator. Also take a Volt meter and check the voltage coming directly off the alternator. Connect your ground wire to the case of the alternator (scape any dirt off the case to get a clean matal contact surface) not to the chassis. By doing this you won't take into factor of (if there are any) bad grounds in the car. If it is normal then take a few readings in varios places on the car. At the Battery terminals, fuse box, etc... If the voltage is lower than the reading you got from the alternaor at any point, then you may have a bad ground somewhere. All garages can check your alternator/battery easily with their equipment without taking any of the components out. It's not that expensive, probably around $30-$40 if not cheaper. --- In dmcnews@xxxxxxxxxxx, Joe Palatinus <jpalatinus@xxxx> wrote: > Great, now my other D' is giving me a voltage problem.
