Voltage regulator question

[noisyone]

My 1966 Lo Boy has what appears to be a burned up and bad voltage regulator. I haven't got around to replacing it yet but the tractor runs fine without it. Could someone explain what's going on here? Why does it still run with a defective regulator and what might happen if I don't replace it soon?

Your battery will go dead. It doesn't take much to run a Cub voltage wise but if it's not charging it will eventually drain the battery depending on how much you use it. I would be searching as to why it burnt up before putting another one on it.

The voltage regulators are very unreliable. Your 1966 is 12 v negative ground correct?


I would put in a 12 volt alternator see recent post viewtopic.php?f=1&t=96696 or if you want to keep the generator contact clover systems for an electronic regulator. It is about the same money and about 40% more for the US buildt regulator which as I wrote is very unreliable.

another alternative is cut the generator belt and charge the battery between uses. You could do that for years!

Hi,
The points in the voltage regulators eventually burn, and make poor contact, then the charging system doesn't work. Usually all that would be wrong is the points are burned, I don't know if you mean that something else is burned.
The points can be filed and cleaned, sometimes the reg will still work, sometimes it won't work.
The ignition system and charging system are separate, so it will run without the charging system working, but only until the battery gets run down, then there is no power for the coil.
It is easier to replace the voltage regulator, than to change to an alternator, if you don't want to do work to it.
