Electrical draw
I bought a 1967 f250. Bought brand new battery for it. It fired up. Went out 2 days later to check co pression and battery was dead. So something is drawing power. Lights were not on. No clue where or how to start finding the cause of the issue. Any recommendations ?

A quick test. Charge the battery, connect the positive battery cable. With the key off lightly touch the negative cable to the battery post. What you are looking for is a spark when you touch the cable and post. A spark indicates a draw on the battery.
If you have a dome light which works take the bulb out before you check for the draw.
If a spark is present, one at a time remove a fuse from the fuse box. When the spark is gone the fuse removed should indicate which circuit has the draw.
