Touched wires for headlight together now no power?.

Have you checked the bulb is good? If that's okay, it has to be a bad connection on the bulb holder or you missed a blown fuse that maybe looks okay.

No power from starter solenoid to starter, also headlights are not switch onas normally

most newer bikes have a fuse on the selenoid itself. if not check the fusebox for bad fuse. also the kickstand switch will not let the bike start in gear with the stand down.

The generator, or dynamo, fits onto the back fork bar of the bike. The top, which rotates, should be close to the tyre of the back wheel. There's a little lever which you press downwards. When you press it the dynamo moves in against the tyre so that when you're cycling the movement of the wheel causes the top of the dynamo to rotate. To stop it, or turn off your lights, you pull the dynamo back out from the tyre. You need to adjust the dynamo so that the top of the dynamo makes contact when the lever is pressed but doesn't when it's pulled back out.

Normally a dynamo has only one wire which connects to the lights. You need to use lights designed for it. This carries the positive current. The frame of the bike usually acts as the negative. Some dynamos may have 2 wires. In this case the positive connects to the centre of the light and the negative to the outer.

I would like to know how to wire a bottle dynamo to bike lights

The bottle dynamo rides against the tire turning it . The wires from it go to the front liht. The same two wires  may also be hoked to a back light. The  direction of flow is not that important but most put the same (one of the two ) wire on the center connection. If you generator has only one wire, then the light(s) will have to be grounded through the frame.

I would like to know how to connect the dynamo lights on my bike

You want to attach this item to the rear of the bike. Mount it so that when you hit the switch the item lean over and hits the rear tire. Hook up the wire to the lights and your all set. Now I can tell you that with this item NOT engaged you will be able to ride with no problems, but with this item engaged it will give you resistance. Meaning that you will know how much harder it is to pedel the bike. I had this item and then went and purchased a battery power item.

Brake lights

The taillight should be on at all times. The brakelight should come on when the front or rear brakes are applied. Start by disconnecting the front brake light switch then the rear to see which switch is broken. Also check the bulbs. I have seen them short out internally. The filament inside the bulb break and contacts the other circuit.
