1970 Ford F100. New Battery, New Alternator. Battery lasts, driving periodically, for about a month. Charge it and is fine for another month. Only thing left to try is coil and solenoid. Can either of these parts cause a battery drain? What else could it be?

the easiest way to check for a draw on a battery is to disconnect the positive cable and place a test light one end on the cable and one end on the battery post. If it lights then go to the fuse box and pull fuses once at a time and replace them until the light goes out. If the light goes out then that is the circuit for that particular fuse. alot of times it's the undrhood light or glove box light that causes this problem. Both of those will be on the courtesy light circuit.
