Simplicity lawn tractor #1686814 with 40 inch deck.  Stopped running while operating, would not re-start. Belts fine and deck fine.  Oil levels fine. Determined battery low, fully recharged but wouldn't hold charge over night.  New battery installed, would not turn over.  Started using my car battery, ran ok.  Confirmed that new battery was good-still will not turn over.  Get click or whining sound.  Did overfill gas tank prior to mowing.

 

Any suggestions on the next move?

The "click" is simply the starter relay solenoid.  Whining sound is usually the starter unable to overcome compression, either from weak/worn starter, weak connection, or automatic compression release not functioning properly, or severely flooded engine causing "hydro-lock".   Many times a worn out starter will work decent with a high amp battery pushing it, but the small GT batteries won't.   What make/model is the engine?

If you get a click you might have a loose ground somewhere. Maybe a loose electrical line somewhere would be my next guess. hopefully someone can help me out here

I did overflow the gas, it spills to the rear of the engine.  Could have shorted something

I recently replaced the 38 inch mowing deck with a used 40 inch synchronized floating deck.  I sense a bigger drag on the engine, but has been working fine.  My suspicion is an electrical short caused by the gas overflow

Pull the spark plug & try to start it.  If it spins, check for fluid coming out the spark plug hole.  If you have fluid coming out, you hydro locked the engine.  Spin it until the fluid stops coming out.

 

Next hook a volt meter to the battery and turning the key to START.  If the voltage isn't 12vdc or more, you have a battery problem.  

 

Next hook a volt meter to the small terminal of the solenoid and turning the key to START.  If the voltage isn't 12vdc or more, you have a wiring problem in your safety switches.

 

If those don't solve the problem, we'll offer more help.

In my limited experience, gas rarely would cause an electrical issue unless it ate the wiring coating or a plastic connector, or (I would put this on the VERY rare end of things)

 

Flames from spilt gas DO often cause electrical issues (just kidding)

 

I would be more inclined to say it's a low current battery + well used starter but I like NCDBO's train of testing.  Start there and let us know what you're finding.

What model do you have? I can find nothing for 1686814. Are you sure that number is right?

Phil, 1686814 is the part number for a 38" mower deck housing.

The mower is a regent model, 14 horse.  I got it running, starts ok, replaced spark plug. But now the electronic clutch will not work to engage the deck.  Could it be a low battery charge?  Loose connection? Any suggestions?

Are you getting 14 volt DC at the clutch?
