Hi guys, I have a 2004 GP GT 80,000 miles. I have had it since late 2003, and only had 1 problem with it (heater blower motor) until now. I have been getting a Charging System Failure light, The voltage jumps around from 13V to over 15V as I drive. The whole electric system shuts off for a second and restartes. I lose my time and date from the DIC. Anyone have any ideals.
