By: IndianaRog Date: July 24, 2019, 7:24 pm --------------------------------------------------------- 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 [/quote] 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. #Post#: 12442-------------------------------------------------- Re: Converted Jensen AC generator to have DC as well. By: Gearhead Jed Date: July 24, 2019, 8:17 pm --------------------------------------------------------- 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. #Post#: 12465-------------------------------------------------- Re: Converted Jensen AC generator to have DC as well.
