Wild cat issues

[Williams1020]

I replaced the blades on my wild cat.
Was mowing along n disengaged the deck to move to the opposite side of drive to avoid theowing rocks at my truck.
Throttled down to engage the deck and nothing.
Throttled up a little and it engaged.
Mowing along and suddenly engine back fires n engine shuts down.
Checked all my safety switches, battery terminals and fuses.
Try to restart and all i get is clicking like the battery is dead.
I suspect safety switch or coil....any suggestions?

Sounds like more than one issue here..possibly a bad or dirty PTO switch.
I would by pass the safety switches one at a time and see if that fixes the issue,,is the clicking coming from the float bowl solenoid or the starter relay,,if its coming from the solenoid then I would lean toward a switch or wire broken ?

Clicking is from solenoind like the battery doesnt have enough juice to engage the starter.
Im gonna rule out safety switch cuz if a safety switch was bad, it wouldnt allow contact to the solenoid.

I am going to say you have a charging problem. Possibly a fuse blown or either a stator or regulator. The clicking sound is going to be because you have a low battery for sure. It would not be a safety switch because the safety switches would have to be made for the clicking sound to take place.

I will note that i have had similar issues with the battery goin dead between mowing but the local repair shop did something to correct it.
Never has it back fired and just quit before.
I might need to just trade it in on a new mower.

So why just suddenly back fire and quit?
Bad stator?

Because the battery is running down.
When running at full revs the alternator is putting out enough to keep the engine running.
Whne youthrottled down the output from the alternator drops sp the fuel solenoid no longer has enough power to stay open & it suts off the fuel supply.

The battery has run down to the point that the mower is running on the alternator output alone.
Slowing the engine drops the output to below 10V and the carb solenoid shuts down.
When the load form the solenoid is removed from the circuit the voltages rises momentarily so it opens back then of coures closes back down.
This fluttering might cycle a dozen or more times before then whole things shuts down period.
You need to recharge the battery then start the mower & check the charging cirucit.
If it checks out OK and the batery holds a charge OK you have a short somewnere in the wiring or some really dirty joints burning up the power.

Just to clarify, the engine back fired and shut down when i was mowing and the revs were at full throttle.
My first thout was alternator because the engine will run off the battery when the alternator quits charging like a car but i dont know mowers.
I know a lil bit about older cars and 2 strokes.

I think that the charging is gone and it is running off of the battery alone. The voltage in the battery is dropping enough that it is not enough current to keep it running. Back firing many times comes from not having current or intermittent current. You can turn the switch off at high RPM and turn it back on and many times one will backfire. Therefore I still believe you have a charging issue not a switch issue.
