I WAS GIVEN A TROY BILT LAWN MOWER WITH A 42 INCH DECK. IT RAN BUT JUST QUIT ACCORDING TO THE OWNER. CAN'T START IT WITH THE SWITCH DON'T GET ANY CLICK JUST DEAD. JUMPED IT FROM BATTERY TO STARTER TO TURN IT OVER SO I COULD CHECK THE SPARK. NO SPARK SHOWED ON MY TESTER. FUEL IS FRESH AND IT RAN JUST 3 WEEKS AGO. I'M LOST ON WHAT TO DO.

Find the fuse and replace it
Remove the blower housing, remove the kill wire on the coil and spin the motor while checking foe a spark
if you get one with the wire removed ans don't get one with the wire attached ( Parking brake on & Blades off ) then you have a safety circuit problem .
Check the trigger wire at the starting solenoid.
With the parking brake on & Blades off you should get battery voltage on the trigger wire with the key in the S position.

I would have loved to have told you where these bits are and what colour the wires are but there are 142 variations of a Troy-bilt that could have been fitted with a 42" deck and no one but you knows which one you have

After doing what BertsM suggested...I would start testing all the interlock safety switches, then the ignition switch and trace the 12v there if you have it.

It's a Bronco if that helps any?

As the guys said, but all the safeties narrow down to a ground connection to the coil. This coil is self powered, no battery voltage needed. Get the black (?) ground wire off the coil and jump the starter. If it runs then start backtracking to find the culprit.

Simce it was just given to you, the previous owner may have tried a new keyswitch, and it may be the incorrect one, as that is a common occurance. Take off the keyswitch and take a pic of the back of it, and post it here. Also find the tag behind or ymder the seat, and post the model numbers.
