Why does my Dynamo Crank not work on my weather radio?

Either the battery is exhausted and need replacement, or the dynamo motor brushes are worn out. Either can be replaced if you know where to get them from. But, had you mentioned the name, model and type of weather radio, I would have helped you better by providing you with a link to where you can get parts. Sorry.

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.

Can we attach both dynamo and motor with giving connections to each other

Yes. If both are matched in voltage and current rating.. the motor shaft will turn when the dynamo shaft is rotated.

Wiring of a Panasonic CQ-C1001N Car CD Player into a Morris 1000

You can get wiring diagrams on line, do a search using the players full name. Is your morris positive on negative earth? you will have to swap it if it is positive as the player is negative earth only (usually dynamo is +ve and alternators are-ve ) I have changed lots over when dynamos were common, turn the battery round and pull the 2 wires off the dynamo take a wire from the +ve battery terminal  and "wipe it across the 2 terminals on the dynamo, this will make it -ve earth too, re connect the dynamo and off you go
