Which Wire Where

I got a new switch from the suggested website. Unfortunately I unplugged all the wires on the old one before noting their placement on the switch. Can you help me know which wire to connect where? I'd appreciate it.

Starts fine runs fine,10 to 30 min shuts down,no spark.30 to 60 min will start as if nothing ever happened. ?

Lets do the easy cheap quick stuff first. Some have a low oil sensor on the engine that will interrupt the spark if it detects low oil so make sure it is full to the mark. The spark plug does go bad so try a new one. Then it gets harder from there, under the fan shroud that covers the flywheel is a ignition module , there will be spark plug wire or two and one small wire plugged onto it, unplug it, this will separate all the safety switches that could be the problem from the engine. NOTE it will not shut off with the key until you plug it back on. Put the shroud back on and try it again. If it stills quits and has no spark I would change the ignition module. If it does not quit it is one of the safety switch. The little wire on the module is connected to the ground through the safety switches to stop the spark and is what shuts it off when one of them are not satisfied.

I have an old John Deere S83 lawn tractor. I put in a new battery and double checked everything, but it will not turn over-no click or anything. Any suggestions? Is there a way to by pass the seat...

make sure blades are disengaged all the way,to disable seat safety switch just unplug if it has a two wire hook up you need to run jumper wire between wire terminals or use a 5 amp two prong car fuse.If that doesn't work check starter solenoid to.

Have hampton bay add on remote control kit on patio ceiling fan. Battery died in the remote, so kid turned fan off with pull chain. replced battery, now cant get fan to work on any pull chain settings....

The pull switch in the fan may be broken in the off position. Luckily these are easy to replace. Purchase a new switch. Obtain a wire stripper and phillips screwdriver. Lower the light (if installed) or the blank by removing the screws. Disconnect light if installed. Unscrew nurled knob on fan switch and remove switch. Make note of where the wires go, I take a picture with my cell phone. Cut wires off as close to the old switch as you can. Strip about 1/4 to 3/8 inch of the insulation off the end with the wire stripper. Insert into the appropriate hole in the switch. Nothing to tighten to lock down here, it will hold it. Reinstall switch and light and test for proper operation.

I have an older Kubota tractor, model B7100 HST. Was running the tractor and had electrical smoke/short? Took the dash off and noticed that the regulator was fried and melted no other apparent damage. I...

I can see where you believe that the problem is in the dash. But I can also see where the mechanic said to trace the wires out. This is a very difficult one to figure out. But before you go buy an ignition switch. I would take the old ignition switch off and check all of the wires to ground. Make sure that you don't have any continuity on any of the wires to ground. Then you can check all of the pins on the ignition switch to ground also. This will determine if it is one of the wires going to ground, or the actual ignition switch going to ground.

I have a husqvarna yth2148 and the blades have quit and then after sitting till the next day they have started working and now it quit completely and wondering if there is a way to test the pto switch by...

Testing the PTO clutch and wiring.
1) A voltmeter or test light is a MUST.
2) Starting at the clutch, there is a connector from the wiring harness.
a) one wire will have voltage, the other is a ground wire
**NOTE: a person must be in the seat, pto turned on. DO NOT start the engine, but have the key in the run position as if you were mowing.
If there is voltage in the wiring harness connector, the problem is the clutch assembly.
If NOT, then
3) check for voltage from the back of the pto switch (normally, the switch can be removed by depressing the holding tabs on it's sides, so that you can access wires easily)
a) you will have a supply wire from the ignition switch, and a wire that goes to the clutch harness. with the switch on, you should have voltage on at least 2 wires. The other wires are the seat safety/start circuit and are not part of this test.
b) If you have battery voltage coming into the switch, but nothing coming out, the switch is bad.
c) if you do not have any voltage supply, then
4) check the ignition switch, does it have a battery source voltage, and in the run position, it normally will have an 'A' terminal that supplies the pto switch
* note
5) many times the internal terminals of the igniton switch can fail to supply voltage to the pto switch
** I am assuming the supply to the ignition switch is good, because otherwise you would not be able to start the tractor..
