I will pass on that experiment😙😄. But there is a significant difference between voltage and amperage when rating electrical devices. I don't think a mag puts out anything like 20 amps, although many switches are rated at 250 volts, rather than the high voltage output of a mag.
I will do my homework in the Bendix manuals and see what can be reported back.
