    Those are all wired "hot" so may be drawing power even though no bulb is present (someone may correct me on this). I've also seen alternators test well but have bad diodes and draw down a battery so perhaps a new alternator may just do the trick. Something to look into.

    Check to see if the Mustang switch in the same era would work.
    Sorry, it's not the switch itself, it's the timer relay.
    Good idea, i'll see if something else might work.

    If you have power seats, make sure the buttons aren't sticking. I had a wagon that had the battery died all the time. Turns out the seat button was dirty and sticking on. WagonMan
