Dynamo problem The radio works fine when it is powered by the solar panel. When I wind it and turn the radio on I get nothing. I have noticed after I crank it the crank unwinds slowly, then when I turn the radio on it unwinds a little faster like power is being used but I get no sound out of it. I have taken the back off but I don,t see any wires lose. Thanks in advance for any help.

In the original big black Baygen radio there is a blue wire with a solder joint that breaks. This wire shunts part of the load back to the generator and prevents it from running to fast and going over-voltage. I am guessing that a similar problem is affecting your newer smaller radio. On the original radio after you take the two halves of the case apart there is a blue wire that comes from the 3v input jack on the back half of the case and goes to the radio circuit board near the top corner. The solder joint where the wire is soldered breaks easily. With this wire broken the generator will run to fast because there is very little load. The radio will still play if you slow the generator with your hand as it is playing back. If you resolder this wire the radio will work and the generator will run at the proper speed. This takes only a moment or two.

Good luck.

If you have the ac to dc adaptor, try insterting the plug (without plugging in the wall). This somehow allows the windup to work on mine, otherwise, similar symptoms as you...

Sometimes the belt stretches out from heat or hours of use, and you can put a small rubber band over the pulley and then place the belt back on over the rubber band to make it work like it should. This gives the belt a surface to grab to turn the pulleys.

Inside the BayGen radio there is a small motor/generator installed inside the spring drive mechanism. The motor's pulley however protrudes outside of the spring drive mechanism. In my case the small diameter black rubber drive belt had simply fallen off inside the case. This drive belt extends from the small metal generator pulley to the large white pulley. It requires gently bending the large thin white cog which basically almost touches the large pulley to get the drive belt to reach the motor/generator pulley. Once the belt was reinstalled the radio in my case worked OK, with a bit of lube on the cogs and a little arm power on the spring winder in the correct direction, to get it started.

I would also like to point out that UNDER NO CIRCUMSTANCES SHOULD ANYONE TRY TO OPEN THE CLEAR PLASTIC SPRING DRIVE CASE, AS ACCORDING TO THE MANUFACTURER THERE IS ENOUGH TENSION IN THE SPRING TO CAUSE SERIOUS INJURY OR EVEN DEATH.
