its a 90 gt thats been converted to carb with a full msd ignition. the issue that im having is that the battery isnt being charged enough to restart the car after being run for about 30 minutes or so. i found out tonight that the battery is back feeding through the alt for some reason. i leave the alt plugged in and it gets hot and drains the battery and when i unplug it the alt stays cool and the battery stays charged. the alt has been replace 3 different times and still the same issue. does anybody have any insight on where to start looking and what the problem might be? please help
