Where is the on/off switch? It is plugged in but no power

There should be a line connect plug within a foot or so from switch...the new switch should come with section of wire and plug on it to plug up

Check the power plug cord, might be bent so often that the internal wire)s) are broken. You can cutoff old plug and replace with new one.

Power switches on most of these have wires that plug in. Once you remove the switch you should be able to unplug the wires and plug them back onto the replacement switch.
These are replaceable items.

does your plug have a reset on it?

You say you proved power to the coil but there is no spark at the end of the spark plug wire ... have you checked that spark plug wire? Could be very high resistance or open ...

Just about every power supply I've owned doesn't have a power switch. The power supply is turned on by one of the wires in the 24 pin connector. According to this it looks to be pin 16 and how to turn it on:

"Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF."

Hope this helps

Suggest you see if the problem is the Power On switch, or the Power Supply.

(First check to see if the receptacle in the surge protector, that the computer is plugged into, has power.
Have had a few bad surge protectors, where just THAT receptacle was bad.

"Hmmm, surge protector power on LED light is lit. Monitor, printer, and router have power, that are plugged into the surge protector.

Plugged a lamp into THAT receptacle, and found it to be bad)

To test whether the Power On switch, or the Power Supply is bad, a jumper wire is used to bypass the Power On switch.

[ The Power On switch is located inside the plastic Power On button.
This is an example of a generic ATX Power On switch, that I have found fits many computers,

The jumper wire is used on the 20, or 24-pin ATX main power cable's connector.
While still plugged into the motherboard.

The jumper wire connects to the Soft Power On wire, (Green), and to any Ground wire. (Black)

Example of a 20-pin ATX main power cable, and it's respective connector,

Using the jumper (Wire) to bypass the Power On switch, turns the Power Supply on?
The problem is a bad Power On switch.

Using the jumper to bypass the Power On switch, does Not turn the Power Supply on?
The problem is a bad Power Supply.

There is a correct procedure for performing this test.

Please check the power cord. The plug and the socket and ensure the wires are connected properly. Check the wall plug and see that it has power. Also check the power cable on a different device. If it still does not work check the connection of plug at the back. Hope it is not loose. Also check the voltage settings. It should be 220/240 volts

the voltage switch should be a small red switch, right below where the power cord plugs in. you will need a small screwdriver to switch it easily.

if you are getting no power at all, i would also check all the wiring connections on the motherboard from the ATX power switch. these are not that hard to dislodge and could also account for your problem.
hope this helps

Just spent the afternoon with an RF4900 with a power problem. The set was intermittent. Found on the back of the set where the ac plugs in, there is a switch that is ingaged when the ac plugs into the set. If the ac cord is old it might not be engaging this switch when the cord is plugged into the set. The switch controls ether battery power or ac power.
