Memory Guard for Electronics

If you'd like to use a battery disconnect switch but don't want your computer or radio memory to reset each time you cut the power, you need the Memory Guard. The Memory Guard hooks across the terminals of your battery disconnect and has a 3 amp fuse in it.

This device permits the flow of the very small amount of energy necessary to preserve your computer's volatile memory, while simultaneously preventing a flow of energy sufficient to start the engine, so no one can steal your automobile and the battery life will hardly be affected! If anyone tries to start your car, it will pop the fuse.

It's ideal for all vehicles with a radio with memory or clock and those running a fuel injection system.
