Charging Problem 2444 IH

tonyaandralph · May 22, 2009

I shutoff my tractor the other day and noticed the battery boiling. I checked the output at the battery and it reads around 18v. I changed the regulator and the generator would not come on, didn't produce any voltage. Put on the old one, same type and they are both only a month old, and get the same 18 volt output. I took the generator, which is also a month old to Autozone, watched him check it and the machine said it was good. Put it back on tractor and get 18 volts. I ran an external wire to the p and f from regulator to generator, just in case I had a wiring issue. No luck.
Now when I pull the battery terminal off, the tractor shuts down. Also, if I disconnect the battery lead on the "batt" terminal on the generator, the "batt" terminal measures 35 volts.
The voltage does not go up or down with the throttle, it goes from 12 volts to 18 in about 20 seconds.
I plan on taking the regulator and generator to Autozone tomorrow and having them check them together. Other than that I am lost.

Any help would be appreciated.

Both VRs may be bad. There are good new VRs on the market, they cost a bit more, but work well and longer. The field winding is grounded to make full output. Thus the F terminal on the Regulator leads to ground through the regulator frame. Testing it is a good idea. Keep us informed. JimN

The 2444 should have a 10DN series AC generator, better know an as alternator.

The regulator has internal connections to both battery voltage and ground. The field circuit of the alternator is internally grounded and needs voltage from the regulator applied to the F terminal to charge. Either grounding or applying battery voltage to the field circuit while the regulator is connected can fry the contacts in the regulator.

Poor or missing grounding at the regulator can lead to overcharging.

I decided to go with an internal regulator/alternator. Scrapped most of the wiring and went with one of Bobs wiring diagrams this morning.

Sits steady at 14.4, blew both my headlights though before I realized there was a problem.

Thanks to you both for your help.

They actually make enough light to see by (but only for a few seconds)I am glad it works. JimN

- Hello -

I realize this post is 2 years old but I'm going to try with a reply, as I'm having a charging issue with my 2444 as well. My issue is that it's not charging at all. I changed the alternator and went with the combined unit - but need the wiring diagram (Bob's?). Any chance you could point me to it? I'm drawing from the batt only, not charging at all. I changed the alternator/regulator but I'm getting the same problem still. I'm going to start changing wires next - but having a correct diagram for the combined alternator/regulator would really help.

Thanks!

Doug
