Small Engines (Lawn Mowers, etc.): Safety interlock module, zero ohms, incorrect position

Question

wiring diagram I have an exmark tt hp s/n 202396 model number TT4817KA.  None of the safety features work.  I replaced the safety interlock module, still not working.  I tested all the switches with an ohm meter and they all worked and I traced all the wires to the connector that plugs into the module and everything is reading through as it should and all the wires are correct according to the wiring diagram.  Is it possible that my new module came D.O.A.??

Thank you.

Answer
Are there any numbers on the interlock module?  If none of the safety features are working then I would suspect the interlock module.

I checked out the Exmark site and found your manual in the archive section.  The parts list has an awesome wiring schematic.  Did you ohm each wire, one by one, from the safety switch connector to the interlock module using the schematic?  

Did you check each wire to see if one may be shorted to ground?  Is the real ground,the black wire connected to ground.  Dis-connect the ground wire and clean the connection and connector with a wire brush.

If the switches, wires and ground test good then the module has to be bad.
All mower ingition systems are basically the same.  To stop the engine the primary coil winding of the ignition coil is shorted to ground which removes the spark.  With any of the switches in the incorrect position, i.e., the stop or non-start configuration, the wire going to the engine kill, the red wire, should have continunity or zero ohms to ground.

CHECK THIS FIRST!!!!!!  Is the wire connected to the engine ingnition coil dis-connected or broke?  You will have to remove the top sheet metal or plastic housing to check the wire.

Let me know about the ignition wire.
