craftsman lt3000, model # 917.276810. my tractor won't start?

i have replaced the battery, starter, alteernator and solenoid with Sears parts.. the engine won't start.
i can crank the engine by touching the two red terminals on the solenoid. Still no start when i turn the key. It wont crank the engine.
new fuel filter and fresh fuel have been added.

the starter and alternator were bad. the only thing my manual says is that the starter switch may be bad. i removed the switch and cleaned it. lubricated switch with dialectric silicone. still no go.

any ideas???

many thanks, David

Thank you for your question.

I am sorry you are having this problem with the tractor. First, make sure the engagement lever is down and the brake pedal is fully depressed or the tractor will not attempt to turn over. If you have already done this, I recommend checking the fuse. The fuse is located behind the dash. If the fuse is good, you have a wiring or switch problem. The easiest way to pin point the problem is with a volt meter. If you do not have a meter, you can purchase one relatively cheap.

Turn the meter to check dc volts, and then hold the black lead to the black negative battery terminal for all of the voltage checks. Place the red lead on the positive terminal of the battery. The reading should be 12 volts. If you have a 12 volt reading, move the red lead to the first blue dot in the image. Your reading should be 12 volts. If you have 12 volts, have someone sit on the tractor and hold the brake pedal while turning the key for the rest of the checks. While they have the key turned to the start position, move the red lead to the next blue dot. The reading should always be 12 volts. Then move to the next blue dot. If you lose the 12 volts, the problem is between the last blue dot you had the voltage and where you lost the voltage. If you have 12 volts all the way to the white wire on the solenoid, the solenoid or the starter is defective.

To determine starter or solenoid short the two large posts on the solenoid together with a screwdriver. There should be a spark it is normal. Once shorted the starter should run.
