International 2444 Alternator Wiring

Hello,

New user here, but saw some active posts on a 444 wiring issue so I thought I would post about my current project. I hope I can get a similar response from users.

I have owned a 2444 for 20 years. The 2444 is the industrial version of the 444. I have the shop manual which is a good start, but my wiring is much worse then what is shown in the 444 thread.

For last 10 years, I have run the tractor off the battery only, as the wiring to the Delco Alternator was a mess with the insulation gone.

Battery would last this way 2-3 years then I would get a new one.

With some downtime from work (Furlough) decided I would try again to get the wiring working by bypassing the harness.

I also purchased a new delco alternator to make sure that was not the issue.
 
My first confusing part is the regulator was still installed in the electrical system even though the tractor was upgraded by previous owner to an alternator.

From what I can read, the Regulator is not used when the generator is upgraded to the alternator. When I unplug the harness to VR the tractor still starts and runs off the battery.

Want to try a few more things before bringing in a professional.

There are instructions online for wiring a Delco alternator by jumping the (F) over to the (+) on alternator and jumping the sense wire (R) through the dummy light to the switch.
 
When I do this the light no longer works. The (R) is not providing the needed ground before the engine is running

Am I correct to assume I do not need a regulator if all the Alternator is doing is charging the battery?

Is there some jumper I need to do at the regulator connector even though I direct wire the switch to dummy light to (R) terminal on alt?
 
I think you need at least 5 posts before you can attach pictures.
As long as it is an internally regulated alternator, you can get rid of the voltage regulator. The charging system is pretty simple. I would rip out all the old wiring and start fresh with the correct wiring for your specific alternator. You can even get a 1-wire alternator and just run a single 8 or 10 gauge wire to the battery and be done with it. With a 1-wire alternator, you usually have to rev the engine up to full speed (on these old, slower revving engines) to get it excited and start producing power. If you use the dummy light as the exciter like it is now, it should start charging at idle. Depends on exactly which alternator you have.
 
I originally wanted all new wiring but ran into an issue getting at the dash wiring

I could not pull the steerin wheel to get at wires Nader the dash so I left the under dash wiring

I tap in at the connector to the VR where I see the switched power

I add in a dummy light that when grounded is on all time

When I connect same wire to alternator it is no longer grounded

If I can't get this figured out the 1 wire may be by next step

There is a resistor bar next to the regulator. Not sure if that needs to be n parallel with dummy light as shown in some diagrams

Other diagrams have the resistor in the distributor circuit

Engine runs without the resistor connected
 
I would say the wiring has been patched and
bodged . The tractor would originally have dynamo
With positive ground
When I worked at IH dealer in 70's in uk. 444 wiring
Problems were fairly common as the wiring
insulation would perish caused by overfilling with
Fuel
 
Run an 8 gage wire from Batt terminal on alt to amp gauge From amp gauge to Starter terminal where battery cable is . With a wire from the Plug next to it the one goes to the batt terminal the other goes to your light or switch. Will charge fine. Plugs for the double plug can be had at auto parts store with leads on them.
 
This is what I have with the exception of no alt meter.

I am reluctant to keep it running long knowing the light does not come on when the Ign is on but the engine is not yet started.

The dummy light works fine when connected to ground and Ign is on, but does not light up when connected to the alternator (1) or (R) post.

I know I have the dummy light connected to the right terminal (1) on the alt from both the wiring schematic as well as the other terminal (2)or (F) will spark when attached to the (+) post on the alt.
