have new battery, starter, alternator distributor cap, wires plugs. Car will start with battery charged but won't hold the charge starts running rough and will just die if foot is not on the gas peddle. Nothing electrical works now, headlights, brake lights, blinkers, wipers, ac-heater nada. With battery charged it will start up but will slowly lose voltage on the voltmeter. Then eventually die. Tried everything and can't pin point where the problem is located. All new fuses but nothing electrical works even with a full charged battery with the ignition in the on position. I'm at a standstill and don't want to pay a handful to a tech when it could be something fairly simple. I've had this car for three years and ran like a dream until now. I read a lot of post from people on this site and finally joined knowing someone knows what the problem is. Hope I explained enough and hope to get this fixed as soon as possible......Thanks people!
