MTD Yard Machines Lawn Tractor Won't Turn Over on Start - Diagnostic Information

Ignition Switch Diagnostic Information:

First you should be able to detect 12V battery power at the B terminal without turning the key (or even if the key is in your pocket).

The B terminal is where power arrives at the switch after leaving the battery. The fuse is between the battery and the B terminal.

Sometimes the switch itself is the "bad connection" and just kills itself (often taking out some wiring with it).
