Stanley Riding Mower start problems with 17.5 Tecumseh (Model: OHV175) engine

I really appreciate some help on this matter.

have Stanley Riding Mower (model: 425605X692) with 17.5 Tecumseh (Model: OHV175) engine.

When ignition key is turned, nothing happens.

Here is what did so far:

1- Battery has been slow recharged overnight (tested and it has power ~12.5V)

2- Carburetor cleaned.
3- Ignition switch seem a little rusted, replaced.
4- Oil and filter replaced
5- Solenoid replaced
6- spark plug replaced

Solenoid gets power.

Still nothing happens when ignition key is turned on.

Any suggestions.. Thanks

So, Where is the solenoid getting power to ?

If you have power to the small wire on the solenoid it should be clicking or spinning the engine over with the key in the start position.

This is a three terminal starter solenoid and there is no power on the small wire when the key in the start position.

there is power on the left side that gets power directly from battery.

OK,

We can assume you checked the fuse correct ?

When you replaced the solenoid did you re-install the smaller red/positive wire back on the same post with the now hot big cable going to the battery ?

There are two safety switches that could be causing this no crank over/start situation. One is on the brake/clutch pedal linkage the other is on the deck engagement linkage. These can be tested with a multimeter set on ohm's scale.


Unplug the switch and put your test leads on the same color scheme wires, If you have a open circuit activate the switch and it should now show a closed circuit, If the circuit is closed it should show a open circuit when the switch is activated.

Good Luck

Yes, though fuse was good, it has been replaced.

Yes for the red wire connection.

Will test those two switches tomorrow morning. Thanks...

Here is a link to the same problem that was recently solved. The same testing procedures should apply although the minor details may differ.

Thanks...

I spend a couple of hours but did not work out. There was no power on the right side of the solenoid for some reason. Called repair guy to pick it up. First thing they noticed when they got here was the order of the cables on the solenoid. Apparently it was important. I should have RTFM when installing new solenoid. Thanks for the help. Hope this helps someone...

It shouldn't matter which cable was installed on which post, as long as the small red wire was attatched to the same post as the positive battery cable.
