Unfortunately my Meadowbrook does not have a clock but my Cadillac 75 has 2 of them. It was explained to me that when the clock winds down the metal tab attached to the winding mechanism comes into contact with the body of the clock. This creates a short which throws the mechanism back up and keeps it wound. When the car sits for a long time without being run the battery wears down. Even though the battery has voltage the amperage becomes too low to throw the clock mechanism. So it heats up and either fuses the 2 pieces together or creates oxidation (correct me if I’m wrong on that last part) that causes the contact to be unable to throw the mechanism when a new battery is put on. In my case, I took the back cover off of the clock, sprayed it with an electrical cleaner, gently cleaned the contact points where the winding mechanism meets the housing and then gently moved the rocking piece that spins back and forth. I don’t know the technical term for that piece. I hooked a wire to the hot stud and the positive terminal of the battery at my work bench and another wire to one of the outer studs on the clock and the negative terminal. It stopped a couple time so I had to keep moving that spinning piece but soon enough it ran nonstop and once the winding got down to the housing it clicked it back up and kept going.
