1970 Hot Wheels Tune-Up Tower: Motor

Usually, the first thing that doesn’t work right on an old Tune-Up Tower is the motor. The motor is housed on the top floor and lives right under the white toggle switches.




The electric motors that Mattel used in the early Hot Wheels line-up powered Super-Chargers and Tune-Up Towers. They were all made in Japan. In my experience, these motors are pretty much bullet proof.

When I get one that doesn’t run, more than 90% of the time it’s not the motor that’s at fault, it’s typically a bad electrical contact that’s the problem.

And the number one cause of bad electrical contacts in Super-Chargers and Tune-Up Towers? Corrosion on the battery terminal posts. Although a slow leak from alkaline batteries left in the battery compartment will produce a white calcium carbonate build up on the negative side of the battery, by far the biggest issue is copper tarnishing. Copper begins to oxidize when exposed to air. Basically, refined copper metal will automatically return to it’s more natural state which is an “ore”.

Here are 3 questions:

  1. How do you access the metal contacts on a Tune-Up Tower?
  2. How do you go from tarnished
    Tarnished copper.

    3. Will the toggle switches and motor work again?
