You have some serious wiring problems, for sure. My first guess is that your grounding conductor and neutral are touching somewhere and your ground is acting as the neutral when the neutral is disconnected.
The light coming on when the hair dryer is used is another mystery.
You need to hire a competent electrician to trouble shoot these problems.

A object without electrical charges.
The neutral wire is the return wire back to the distribution panel from the load. Without this return wire no load will work.
The white wire is neutral. If you need 110V at whatever this is supplying you need to connect it to neutral (Not ground). If you only want 220V you can simply cap it with a wire nut at both ends and leave it unused. If you can connect it do neutral, do so. The next person will expect it to be neutral and it is better to have it tied to neutral than floating. If in doubt, go to your local home improvement center and buy a book. It will teach you how to do it legally and will serve as a handy reference during the job. Finally, I will add do it right or don't do it at all. If you are negligent you could easily kill someone through fire or electrocution. If you read and do your homework and learn what it required you may find that small electrical repairs can be quick and easy. If you can't understand what you need to do hire an electrician. The cost of a professional is not worth the time you will waste if you don't understand what you are doing and the danger therein.
In the atom the particle without electrical charge is the neutron.

You install the plumbing along with the bathroom.
If you disconnect without turning off the charger, the sparks caused may ignite the hydrogen discharged from the battery while charging.
Usually, the line feeding the recepticle has a collar that simply slips back away from the recepticle (You may have to push the line forward and then pull back on the collar.) Then it should release.
The object without charge is called Neutral object.
Without the corresponding software for the system throwing up codes, the only thing you can do is reboot the ECMs... disconnect the batteries, let them stay disconnected for about 15 minutes, then connect them again.
