Too Many Amps

I have a 1949 International with a 6v, positive ground, generator and regulator. My regulator always puts out a lot of amps--around 30 and never goes down. I have a new battery and with all the amps being pumped into it, I'm afraid it will burn it up. I have to add water every so often because the water boils out of it.

How do I adjust the regulator so that it has the generator charge fewer amps and when the battery is fully charged, go to close to zero amps. The battery, generator and regulator are all about a year old. The symptoms I described have been that way since I installed the new generator and regulator.

I appreciate the guidance.
 
Your generator is putting out too many amps because the voltage regulation is not working correctly.

What model tractor is it?

This is actually an International KB-3 pickup. I thought the tractor talk forum would have the most knowledge and traffic.
 

Can you point me in a direction to double check installation and adjustment of the regulator?
 
Disconnect the F terminal of the generator. If is now goes to slight discharge when running, you know the F terminal is working correctly in the generator. (not internally shorted to ground, or field to ground internally. You also now know that the regulator is not regulating correctly. This means you can try to adjust it, or just get a new one. Adjustment is done to the internal relay that has smaller contacts. It involves adjusting the tension on the spring that pulls the contacts together. Loosening this spring (a tiny bit) reduces the output. Some cheap regulators have a metal tab that must be bent. Others have a screw to turn. It must be done with a fully charged battery. The voltage should be about 7 to 7.2 volts when running 2/3 throttle. (do not mess with the other big contact relay. The cover will affect the adjustment, so putting it on for testing is a must!.

Looks like you've got the advice you need. Be aware that many of these new regulators are junk. So if you're hooked up correctly, you may want to check with your supplier to see if or how much they'll stand behind this regulator before you start messing with it.
 
If its always in the full high charge mode the battery will boil over and outgas excessively as youre aware. Possible reasons are its miswired or the VR is faulty or the Gennys FLD post is shorted to ground somewhere. Similar to Jims post remove the wire on the Gennys FLD post and see what happens??? That should reduce the charge drastically. If so the VR is bad or miswired or theres a short in the wire from FLD on genny to VR. If it still charges max the gennys has an internal field short such as the nut was overtightened causing a dead filed winding short.

NOTE OF CAUTION this is for a Class A charging circuit. If it has a Class B things are different. I trust your VR and genny are matched and for the same (Class A or Class B) system.

If your gen has movable brush -losen the locking screw on end of gen & rotate brush in direction of rotation to reduce output -against rotation to increase output.
 
Thanks everyone. Got a lot of farting around to do this weekend. I will let you all know how it goes.

Thanks again!
 
You need to start with what gen you have then make sure yoou have the correct regulator for that gen, Is it mounted on the gen you have no way of knowng just whhat the previous owner did so that would be a place to start just because you have a reg it doesent mean its the correct one for your gen get that # and go from there.
