Change the outlet to a grounded one. Get an adapter that goes from 3 prong to 2. Break the ground prong off. Any one of these will work.
Answer for USA, Canada and countries running a 60 Hertz supply service.If you replace an ungrounded outlet with a grounded outlet, the tester should show an open ground indication. The left light will be the only lamp that will light up. Install either another ungrounded outlet or a GFCI receptacle.. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
If your trying to plug in a 110 Volt lamp into 240 volt outlet the answer is simple. You must buy a step down transformer, or your lamp will burn out.
No, the plugs are different to prevent this and even if you could the lamp would be very dim.
If the load is not grounded and has no connection to neutral then nothing should happen. This begs the question of why you would do such a thing. If you touch any metal part on the load you will likely get a shock.
The one wire carries the electricity or voltage. The lamp is grounded completing the circuit. You don't. The light switch is only half the circuit, a lamp has nothing to ground to so it can not work. If the wire to the switch is 3 wire, the bare wire would complete the circuit and power the plug, but it would not be up to code and could present a fire hazzard.
John Howard invented the electrical outlet in 1924. Prior to his invention lamp bulb plugs were used to connect various household appliances.

Plug a lamp into a working socket of an outlet to ensure the lamp works. Then turn off the switch and plug lamp into all outlet sockets, top and bottom outlets until the lamp doesn't light. Then turn on the switch and the lamp should light. Often a switch in a bedroom is only connected to one socket in a duplex outlet. It is possible to remove a jumper in an outlet to isolate the sockets for just this purpose. Often an electrician will install the outlet upside down (The third prong pointing up, to identify the outlet.

Use a voltmeter. The normal choices in the US are 120 v and 240 v. If there is no voltmeter, use an ordinary cheap 60 watt lamp. If the lamp lights normally, the outlet has the voltage marked on the bulb. If it's too dim, the outlet has a lower voltage. If it flashes and dies, it's a higher voltage (I said use a cheap lamp).
No, the plugs are different to prevent this and even if you could the lamp would be very dim.
Theoretically, you could connect three identical lamps in star (wye) and connect this to the three line conductors. But as you asked how to connect a (single) 230-V lamp to the supply, then the answer is by using a step-down transformer.
Generally assume it's the coil as that device runs hot and at very high voltages. Take a small 12V DC light, solder some wires to it. Connect one lead of the lamp to the coil low voltage lead going to the coil. Connect the other side to ground and crank the engine. If the lamp flickers or flashes it's a bad coil. If the lamp stays on put the ungrounded lead on the other low voltage post and re-test. If it flashes then its the coil, still no flash at crank and it's the pickup.

Yes. If the plug (cap) end of the 250 volt lamp is compatible to the receptacle the lamp would work. The light output of the lamp would not be very bright. Because the working voltage is halved so would the light output.
Are you saying that you plug in a lamp and another lamp on that extension cord goes dimmer? If so then the extension cord wire is of a smll guage size and causing a voltage drop from the outlet to the cord output.
