       Converted Jensen AC generator to have DC as well.

       Had some help with this one, but it works as AC and DC current
       generator.

       excellent work Jed, that has so many good possibilities.
       pretzel PA. has done it again 😉👍
       (brilliant idea utilizing the phone charger)

       Jed, now you have to explain HOW you pulled that off...  Also,
       can it produce AC as well or has it been converted to DC only.
       I asks because I once tried hard to make a Jen 15 produce both
       AC and DC like on original Jensen 51's, but I failed to pull it
       off.
       Never too old to learn how it's done.

       Rog, it was mind numbing at first, but I had someone explain it
       to me simply that it all made sense. I don't have an electrical
       engineering degree, but I do understand how it works.
       I have tested the generator on a #55 and it does produce AC and
       DC current. When I have a DC motor attached to the leads, it
       runs. When I touch the leads to the light post side and contact,
       which is the AC side, the motor will only pulse back and forth.
       This is how I truly knew that this was truly AC/DC. Not only
       that, but I can hook a 9v battery to the leads and it will run
       as a motor.  The light bulb knows no AC/DC current. Electricity
       only knows path of least resistance and the tungsten in the bulb
       is the resistance, so that's why it works. Why does a 2.47 volt
       bulb not burn out when hooked to a 9v DC charger? The windings
       in the armature create enough resistance to drop thw voltage and
       that is why it doesn't burn out.

       I hooked my voltmeter and a Shurite gauge to the leads and it
       only produced more than 2v DC. It produced about the same volts
       on the AC side. Remember, AC bounces back and forth. DC goes in
       one direction like a battery.

       Nice work Jed.
       Do you have a wiring diagram?

       Wish I understood how it works but regardless I think it's
       pretty neat.
