Trying to program intertek dvd player to my philips universal remote any codes


You have this backwards; codes are in the remote. Use code search to find something that handles some or all functions of your Intertek DVD player. If a search through all codes stored in the remote fails, you may have to try a different universal remote

John Deere x300 series 2009 model I unhooked the kill wire and it started. But now my mower/pto will not engage is there a way to bypass the sensor?


Based on the combination problems involving the coil kill wire and the PTO activation, I would suspect the PTO switch is bad.

I do not have a schematic for the 300x, however I most of the functions are comparable to the LA 145, 165, 175.

The PTO switch is a multifunction switch. It will have 3 to 4 different functions internally. On the LA 175 it serves 3 functions. These 3 internal functions are independent of one another. Electronically they are known as single pole/single throw switches. In other words even though they are all housed inside a single unit they act light 3 separate light switches in your house.

One function ("light switch") controls your cranking system. When the key is turned to Start, power flows from the Key switch (purple wire) to the PTO switch. With the PTO switch off it flow out (purple/white) and goes to the Brake switch. If the Brake is set the power flows through to the starter solenoid and your engine cranks.

Another "light switch" inside the PTO switch controls the Blade Clutch. Power flows from the Key switch, in run position, (yellow wire) to the PTO switch. With the PTO switch on it flows out another yellow wire to the Blade Clutch. A DC volt meter should show 12 volts switching on and off as the PTO is turned on and off.

The third "light switch" completes a Ground Path. This ground path is a totally separate pathway running through the PTO switch. The ground system is fairly complex because it operates differently under different scenarios.

To produce a spark, the key switch must be in the start or run position. While starting the PTO must be off and the brake set. The seat switch does not matter at this point.

Once the engine is running the seat switch plays a part if the PTO is activated or the Brake is released. Someone must be in the seat.
The Kill system is activated
  1. When the key switch is turned off.
  2. When the operator leaves the seat without setting the brake and turning off the PTO.
  3. When the machine is reversed while the PTO is engaged and the back up switch (RIS) is not pressed.

So there are three different paths to ground; any of which can kill the engine by grounding the coil. Except for turning off the key, all other grounding functions flow through the "grounding light switch" in the PTO.

Because you have a combination problem, the Coil kill wire is grounding the engine and the Blade Clutch won't activate the blades; both of which are affected by the PTO switch, odds are you have a bad PTO.

Obviously there are too many complex functions to just bypass the switch. You will have to replace it. The part number you need is AM135131. You can do a site search to locate and order this replacement switch for about $26.00 including shipping at this site: GreenPartStore Parts for John Deere Lawn Tractors John Deere Lawn Garden...

Why does electric clutch click and seems to be getting no spark


While sitting in the seat with the ignition key on you should be able to hear a click from the pto clutch when the pto switch is activated but this click is audibly different from the click of the starter solenoid. The starter will be disabled if the pto switch is on. If you hear the pto clicking while trying to start then there is a failure in the pto switch. If the starter solenoid was bad the starter would not engage. Check ignition switch, pto switch, and look for wires melted together. Also be sure grounds are good. PTO clicking on start and no spark could have a relation with the pto ground and engine kill wire.

42 Gear model mower blades won't engage


You haven't said if its an electric clutch or manuel so I presume it is electric and controled by a switch(PTO) on the dash 2 reasons.
1 one of your kill switches is faulty example: seat switch which is in an inline circut with your PTO switch could be the problem or a fuse or a bad PTO switch, it usually is the seat switch but trace the wires down from the PTO switch
2 you could have a faulty electric clutch which is under the motor attached to the crank shaft. check the plug in,Does it engage ?sound of a large click and if it does that means the clutch has to be adjusted using a feeler guage.

Wheelhorse 314 engines dies when pto is engaged


I am assuming you have a manual PTO clutch since you did not mention a PTO switch. The starting circuit generally is a series of switches wired in line (series) with each other. You have bypassed the seat but there is usually a switch for neutral, PTO, oil level, and clutch. You will need to trace the wires from one to the other to find the problem. If the seat has a double switch (3 or 4 wires) it is wired through the PTO switch which may be a double switch to short out the ignition so that part of the circuit should stay open to operate. If the oil level is ok and the oil has been changed as recommended you may better consult a Wheelhorse service person. Bypassing the switches is for testing only! I DO NOT RECOMEND LEAVING ANY SAFETY SWITCH BYPASSED. Any defective or out of adjustment switch should be replaced or corrected.

I have no power to the pto on my LT1042 mower I found broken wires and fixed the but still no power. Where are the fuses that would blow? I only found one fuse and its ok


Did you check for power at the pto switch? Start with checking that, then check the wire from the PTO switch to see if it has power all the way to the PTO clutch. If there is power to the clutch, and the belt is good and routed properly it's probably the PTO clutch.

sounds like your electric clutch is prob bad check to make sure wires are not bare touching something, the clutches do go bad eventually like any other electrical part, disc the pigtail and try fuse, if it blows then I would consider a clutch

My LT1045 blows the 20 amp fuse when the Electronic PTO is engaged.


you have to start with the switch and see if its faulty
see if you can replace it temp with a toggle switch
and check the wiring back to the pto as well it mite be grounding out

On a CubCadet MTD pto switch,where does the black wire go at the other end?This is a 13A-212F100 model


I found a parts diagram for your model, but unfortunately, not a schematic that would show the wiring itself. You may be able to figure it out with some patience. There are two circuits that pass through the switch. One has a lead bringing power (+12V) from the ignition switch, possibly via a fuse; another wire takes this power to the PTO clutch. The second circuit is a safety interlock that kills the engine if you are not in the seat when the PTO clutch is active. It may come from the seat switch and go to a kill relay, but there are variations. Tell more about your trouble symptoms and maybe we can figure it out.
