E3L dynamo I'm confused
« on: 23.08. 2016 22:17 »
I have a 1960 A10 which i converted to 12v negative ground using a DVR2 regulator, flashed the dynamo for negative ground installed new battery.I have less than 1 volt output from the new regulator. I did a dynamo test connecting d&f terminals together, on idle i get around 7 volts on my volt meter  if i rev the engine up to 14 volts. I disconnected the new regulator and reinstalled the old lucas 6 volt regulator and had a 7.5 volts output from the regulator. If i'm getting 14 volts from the dynamo that tells me its working or am i missing something. Has anyone had any experience with the DVR2 regulator it  appears i have all the wires connected per the instructions. very frustrating.

If it is connected properly and substituting another regulator gives output then it seems that the DVR is buggered.

Better yet, just talk to Mike at Dynamo Regulators or PM him through the forum. He should be able to answer your questions specifically and immediately. Here's al link to his profile page: http://www.a7a10.net/forum/index.php?action=profile;u=307

Tonup, I have not had any experience with the DVR2 regulator, but I have installed 2-12v, pos earth, solid state regulators to my '61 SR. 1 overheated after about 3 years and the the other, a Boyer unit, has lasted about 10 years. However whilst the 1st one (forgot the name) gave me about 13 volts when a meter was connected to it, the Boyer gave me only about 3 volts. when I called my supplier, he told me to connect it to the battery and then measure the voltage, and sure enough I got 13 volts. So be sure that you aren't getting the required voltage. By the the way, I think you generator should be putting out a bit more too, mine puts out about 22 volts, with the original 6 volt armature.
all the best
Clive

Clive, it depends on how fast you rev the engine as to what output you get.
14V at around 2000 or so revs is OK.
