Greetings,

New to this site and need help with my mower. My Ariens Zoom 42 won't turn over. When the key is turned, not even a click. Battery not the issue. I jumped below the solenoid to the starter and it turns over but won't start. Any help is appreciated.

By the way, this has been a great mower (and still is, I hope). Have had it for 4 years with no issues.

Need to check the connections at the key switch for corrosion as well as any safety switches. Could be on the parking brake, direction control levers, pto switch, The no start could be related to the above, but could be something totally different.

I would start by checking and testing the safety switches, and the key switch. Then figure out the no start from there.

Not familar with your particular mower but in general.
Mowers have 2 safety circuits.
One set of switches isolate the starter solenoid ( which you have bypassed )
And the other grounds out the magneto wire so no spark which is why the mower did not start
This becomes very tedious but you are going to have to check each & every switch and the wires that go to them.
The magneto switches are all normally open generally wired in parallel with each other and close to earth out the spark.
The solenoid switches are all normally open & close to allow power to the solenoid trigger to crank the engine and are is series so all of them must be closed.
ie you must be on the seat, brake on drive in neutral & pto off or the mower won't crank so these are wired in series.
generally the starter wires will be pink, yellow or orange and the magneto wires will be black , green or purple.
ow to really confuse the matter there are interlocked switches like the drive levers & brake. So any one switch may have up to 6 wires ( 3 pairs ) and the interlocks may be either open or closed

In general the starter switch draws power from a wire on the hot side of the solenoid which is fused.
This goes to the "B" ( battery ) terminal on the starter switch.
It makes contact with the S terminal ( Solenoid or start , ) and from there to the PTO switch ( as it is close ) then to both of the direction arms ( oft a relay with both arms connected to it ) then the brake then the solenoid trigger wire.
So if you pull the plug and jump these two wires together ( B & S ) it will make testing easier as you can follow the 12 V with a simple test lead
