| Nov 6, 2021 at 5:27 | comment | added | hacktastical | See your other Q. I had to think about it for a bit. | |
| Nov 6, 2021 at 3:34 | comment | added | David Maher | A PWM, control would be fantastic Hacktastical, but I'm afraid that without some sort of diagram, it would be beyond my current capability. Are you volunteering? I'm a regular visitor to the Dunhackin website, and I have got many valuable resources from there. | |

| Nov 5, 2021 at 23:34 | comment | added | hacktastical | It would be an interesting project to make a PWM control for the field coil that models the way the old regulator works. Basically, sense the voltage, and if it gets above a threshold, start interrupting the field coil current. Maybe a comparator, a 555, and a good-sized FET? | |

| Nov 5, 2021 at 21:07 | comment | added | David Maher | Your solution that you have proposed at vintagetriumphsupply.com/… would work, as would matchlessclueless.com/electrical/lucas/regulator-replacement . The latter is a DVR2 regulator, which is commonly used on Vintage bikes. I was already aware of these options, but was hoping for a less expensive option (I know it's not sheep stations anyway). After a bit of thought, I realize that using a buck boost solution would require the field coil to be energized continually, which would both put unnecessary strain on the dynamo. | |

| Nov 5, 2021 at 10:16 | comment | added | David Maher | You are right and this is exactly the plan that I was going to follow. I'm sorry that I don't have enough points to up vote your answer. I was trying to use a solid state solution instead of a pseudo mechanical regulator. | |
