Voltage regulator

[WFE270NWIA]

It was 50 degrees today so I thought I would start a few tractors. The 300 wouldn't start, not surprising since the battery's over 10 years old. Put the booster pack on and got it running. Left the pack hooked up to read battery voltage. It started charging 13 volts and kept creeping up the longer it ran. After a half hour it was up to 16.9 volts. Voltage regulator is a cheap one from ASAP. Would a bad battery cause this or should I try to adjust the regulator. Thanks.

more info please. its a 6 volt tractor

Unless it is a John Deere 300. Industrial or Lawn and garden there is a 300 in both. Lack of info strikes again

Add 300 Case from the fifties.

Same as the M and valves few days ago. They seam to think we are god and can read minds

Towards your question generally if a battery takes a charge and holds its for week or so and will then start the machine it is installed in, it would most likely not cause a charging system to over charge. Before anyone tells you to adjust the regulator we need to know how long has it been on the tractor? Did it function properly for any amount of time? The problem with less expensive voltage regulators often is the material used to make the contact points is less expensive and not as resistant to burning away and loosing their ability to hold a consistent contact. That higher quality contact material provides that contact stability and also make the regulators equipped as such last longer as many of the original ones did years ago.
Beyond this knowing the machine it is on would help us know if it is an “A” or “B” circuit system so additional troubleshooting can be applied towards your problem.

You're right, it's an IH 300 row crop based off of OP's previous posts.
Also most likely it was converted to 12 volt, as 13-16.9 volts would not be kind to a 6 volt battery.

i realized that, but was wondering if he had an alternator with reg, or the generator with the reg. then new style reg. with electronics' in them are a none adjustable thing. plus no info on the battery if it was load tested which i also presumed not. and saying the reg.is the cheap one ? take the cover off and let us know.

I have been on this forum long enough to know about looking at previous post and I did that. You must have had to go quite a ways back, I think there were recent posts about 4 different tractors that didn’t match up to 300 so I quit. I didn’t feel like going that far out of my way because after all it is important information for his thread that he chose to leave out.
PbIH, do you happen to know about private (Direct Messages) on this forum? You might want to check out why there is a number by your envelope icon at the top of the page, in other words click on it. I sent you something about a week ago, If you chose not to reply I can also respect that.

300 Farmall,12 volt positive ground. Regulator is 6 years old maybe more not sure. Tractor has an amp gauge so when I put regulator on seen it was charging good to go. This was first time I checked voltage when it was running.

As for the condition of the battery would it restart the tractor after it had been charged? Are you using an analog(needle scale) meter or a quality digital meter? If not I wouldn’t trust the voltage readings. Does the ammeter show a charge and then drop back a bit after time? If so it all is probably good and your readings are suspect. You said “tractors” plural, which would mean you have more than one. Any others on 12 volts? If so swap a battery out of one of those supposing you had one that started on its own and repeat your test, only with a meter that meets the “good” criteria above.

Try using a VOM (multimeter) not your booster pack. It doesn't seem the booster pack would affect the charging rate, but it is best to use a test meter, not add a possible outside factor, then go from there.
