Can you burn out ignition switch on 1972 Chevy van by leaving it on the on position until battry dies?

Yes, leaving the ignition switch in the "on" position on a 1972 Chevy van can lead to burnout of the ignition switch and other electrical components. This is because, in the "on" position, power is continuously supplied to several systems, which can cause overheating and eventual failure. Additionally, draining the battery can lead to further electrical issues when attempting to restart the vehicle. It’s always best to turn off the ignition when the vehicle is not in use.
