I have an '87 convertible with an electrical problem. The battery discharges totally in two days if the car is not driven. The battery is new, the alternator is operating properly, and when driven, everything appears normal. Obviously there is a power drain with the ignition switch "off". I connected an analog amp meter inline with the pos anode of the battery and with the ignition off, measured about a 5 amp drain on the battery. I would appreciate any suggestions where to start looking for a power drain of this magnitude.
