diode's but only 4v ac and 1v dc,i was told ther was a way to restore the manetism to the unit by flashing, but the process was not explained to me, need help have to units and both have same problem,and everything in both units check the same,but can't find anything wrong.

No generator will completely contain the magnetic field within the generator casing. It only takes a little residual magnetism to get the generation process started. The previous link is correct in all ways, but I would be tempted to try a strong permanent magnet attached to one side of the generator housing during a startup to see if that would cause enough field imbalance to start the generation process. It is much easier to do and cost virtually nothing. You can remove the magnet if the generator comes back to life.

After the generator will start to generate a magnetic field, it will excite the generator into operation. The generator was probably neutralized by one or more overloads that caused the AC fields to collapse. This is a secondary safety factor beyond the circuit breakers. If this happens again, I would consider getting a larger generator unit.

Thanks for the help, found out today how to flash the unit by 110 ac source,took only five minute after you build the exciter, gen. now working, only ran unit for about 2 minutes this morning and this afternoon it would not work again, then i did the process again and ran the unit for about five minutes and its still holding, will try again tommorrow to see if it retained its charge.
