My engine start button went out so I installed another momentary on button does not do anything. power is good all around. But the button does not turn engine over...any ideas? 2000 r6

Try bypassing the power button by jumpering across the two terminals. If the set doesn't turn on, it's not the power button, it's something more serious. If it does turn on, just replace the power button with any momentary switch.

If the computer started giving you trouble turning on before it failed, it is probably the power supply and not the switch itself. To check, you will need to take the computer case off. There are usually 2 power switches on a pc. The first one disconnects the incoming line voltage completely. Make sure this switch is on before you try the other power switch. The second power switch actually starts the computer. The power disconnect switch is a toggle (or latch), that is, it retains its position. The switch that actually starts your pc is a momentary contact switch. To test the momentary start switch, you will need to take the cover off. Be careful not to damage anything and watch out for exposed voltages. If you pay attention, it is not dangerous. All you need to do is short the 2 wires that go to the case switch momentarily. Once shorted, the motherboard latches on until a power failure or shutdown. Note that you do not want to keep the 2 switch wires shorted, since this will prevent the pc from booting. Just short them for about as long as you normally push the power button in. If the switch is bad, they are not usually difficult to replace. You should be able to find a part number on the switch, as well as manufacturer. While it seems like all the case switches are custom per model, they are not. The actual switch itself is actuated by a plastic button on the case.

Hello. The motor switch may be faulty and may require a new motor. Less likely is the start switch itself but usually this is just a momentary switch which gives power to the motor, if the motor switch is bad it will just go off when you let go of the start button. Dryer motors are usually around $125 plus the labor to fix it, an hour minimum. If the dryer is older I would just replace the dryer as you can get a new simple one for $250 often. Fewer bells and whistles the better. Hope this helps. Good luck.

the power button is a momentary contact switch
so if the set is not coming on and the fuse is good
you probably have either a power supply problem or a horizontal circuit problem which is why the set is not starting up

flyback transformers are know to fail on these models

The motherboard has a pair of pins that is connected to the switch. The switch is a momentary contact, and when depressed the motherboard detects the momentary contact and starts up.

You can use any momentary contact switch as a replacement

seems like your key is not being recognized, possible your tumbler..the ring around your ignition switch is bad

Fords use under hood mounted starter relays. They look like a mine withe 2 large threaded posts abd two small threaded posts. Ignore the two large cable posts. If only one small post has a wire on it, remove wire and try to start engine. If no crank, put back on and try cranking. If it cranks then that is the wire you will put juice to with the other side of the in hand momentary button" connectected to the hot big past. Battery cable big post. Note! momentary button only. be safe, you will be too far from the brakes. Always block wheels. set parking brake. make sure trans is in neutral or in park Do not use remote starter while standing in front of the vehicle or while under the vehicle.

Unless the power button sticks or does not pop back out, i doubt the issue is in the switch, but it can be tested by replacing it with a momentary switch from Radio Shack (not an exact fit, but good for testing)
This sounds like a power supply issue. That would be the first thing to check. If it is NOT connected to anything except the power cord , it shouldn't run unless switched on.
Could also be the motherboard, but before you start dismantling the computer , check the obvious. Open the case (usually to screws on the back) inspect all the cables, reseat your ram chips and addin cards.
Not to scare you ar anything, some of these presarios have bad capacitors on the mother board. coupled with the fact that they are difficult to clean (inside) and airflow is not maximized in the case, they tend to cause the capacitors to swell and leak, losing voltage.
When you are inspecting the insides of your case, take note of any capacitors (little cans with crosses on the top) on the main board inside around the CPU fan that are swollen or leaking.
If you find these in bad condition , i would replace the motherboard.

hmmm...try it with the battery removed only on AC power..
