1988 951 Battery Drain


Vehicle Information: Model(924/944/968): 951; Year: 1988; Body Type: Coupe; Total Mileage: 130K;

I have a battery drain. After charging fully from an AC trickle charger enough to start the car drives normally with no other trouble and high volt reading. But once shut off the battery will drain down so quickly that immediately there is no power to restart. Before I check all the wiring for shorts is there a common problem with these cars? Would the alternator be supplying enough power for a steady voltage reading but the battery still be draining while the car is being driven? Unattached the battery will hold a charge for a couple of days, but wired in it will drop immediately.I would appreciate any help for this problem.Thank you,Eric
