  • Voltage regulator
  • I have an 8N converted to 12 V DC generator through changing the coil winding. It is wired as type B generator. I installed a new C0NF10505A voltage regulator . The generator charges for 2 or 3 minutes and then suddenly the amps go to zero. Checked voltage and did not increase with rpms. After tapping the VR, it starts charging again, with the same behaviour, after a few minutes, it drops to zero. Sometimes when I start the tractor it starts charging and the same happens again. Sometimes, the amps meter oscillates before it goes to zero. The generator runs motorized and all cables were checked for continuity and insulation. Ground wire was checked also. Is there any thing I can do to repair the VR?

  • Re: Voltage regulator
  • You asked this a few weeks ago and I thought then we concluded your best solution was to discard the 12 volt generator and voltage regulator and simply switch them out to a 12 volt alternator. You said then you couldnít get an A Circuit type vr in your country so changed the generator to 12 volt yet still canít seem to get a voltage regulator that will work. They ALL canít be bad! Iíve suspected from the start the problem isnít in your voltage regulator it must be in the other wiring, possibly the 12 volt generator. Do you plan to just keep buying voltage regulators till you maybe get one thatíll work? Good luck.

  • John Patrick, It is true that I presented a similar problem before, but at that time my conclusion was that the regulator was defective. That is why I bought a new one, BTW, both were bought in the US. Tapping the regulator was new to me, I thought that this could recall to more experienced forum participants to identify the problem and perhaps they could have a solution.

    I thought that the primary purpose of this forum was restoration and not having an old machine back to work, no matter how. That is too easy.

    It is very difficult to buy 6 volts batteries in Chile thatís why I converted the generator, trying to keep itís originality and I will continue trying to get a good regulator. I am pretty sure that the electrical system is correctly wired and working properly, but the regulator, is not. I wired the generator as type B as per the forum recommendations. Today I chatted with the regulators seller explaining the situation and he told me that the regulator was defective and they are going to replace it.

    I didnít want to say this, but I have a degree in electrical systems, so please letís raise the conversation to a technical level.

    Curiously, your name, John Patrick translated to Spanish, Is exactly my name Juan Patricio

  • Re: Voltage regulator
  • Exactly my point Juan. In your previous messages you said 6 volt anything was hard to get in South America so that being said, why bother with a generator and voltage regulator if you were getting a 12 volt battery? I'm just trying to see the logic, but it is your tractor so switching the generator to 12 volts was your choice. If it were myself, and 12 volts was all they had, the decision to just go with an alternator would have been a done deal. I still say there is something hinky in the wiring. Every voltage regulator you get has been junk out of the box and I don't believe that at all.

  • John P...why even post when you are not offering any help or information related to his problem, but rather opinion & criticism?

  • Re: Voltage regulator
  • The best thing you can do is trash that regulator and purchase a good quality US made regulator. They are expensive but they work.
