I have a MTD Hechinger mower model 146-834-372 with electrical problems. I have chased out all of the wiring but am not sure of the internal functions of the ignition switch. Any one know of where I can find this information? I cannot find it on the MTD site. The switch is a standard 5 pin with the MTD part number 925-0267B.
Thanks.

There should be letters stamped either on each blade terminal, or beside each terminal on the switch.

How do I find a wiring dirgram for a hechinger model number 146-834-372

Hi,
This is the schematic from a machine two years older. I have reason to believe that I could not find a newer one is tha it did not change for a number of years.
Peace,
Clarke
