Charging system 1952 cub

Postby Workinprogress » Wed Jul 20, 2022 8:33 pm

Working on electrical charging system but getting a little confused on what have and where to go.

System running 6 volt battery with positive ground and a magneto.

Currently has delco 1100501 generator with 3 brushes.

Has Voltage regulator which is mounted on top of the generator.

It did have a 4 way light/load switch which I replaced with a standard 3 way switch because all the external connections contacts were badly corroded.

I also just replaced the entire wiring harness with a brillman harness set up for regulator.

Currently I get no reading on the amp gauge (to the right) when the tractor is running. I wanted to try the headlights to see if gauge does anything but both bulbs burnt out. Figure a quick stop at the local autoparts store would find me a couple bulbs. Three stores, all failed. Was able to rig up 12 volt bulb with test leads and got amp gauge to go a little to the left when I turned the lights on. So I think the amp gauge functions.

So before I start down the trouble shooting path does the system seem correct? Specifically that model generator with a voltage regulator using a 3 way light switch.

you need to back up, you have a cut out relay, not a regulator and the 4 way switch controls it, 3 way switch was not, here is a flow chart for the cut out system

Hi,
Tim, he said it's a 1952 Cub, they have the 1100501 generator, and the voltage regulator on the plate beside the gen, not on top of it.
They also have the 3 position light switch, for only the lights.

IH started using that at serial number 115403.
Check your serial number, and be sure it is a 1952 Cub.

I don't know why the voltage regulator would be on top of the gen if it is a 1952 Cub.
Someone changed it I guess.
Below is a page from the 1955 Cub operator's manual showing the Cub with the hood off, you can see where the voltage regulator is.
The voltage regulator has 4 posts for wires to connect to it.
The cutout or Relay IH called it has 3 posts for wires. It was used up to serial number 115403. It is mounted on top of the generator.
There are voltage regulators made that mount on top of the gen, IH didn't use them on Cubs, they aren't in the Cub parts manual.

The tractor is probably earlier than he thinks.

try and post a pic of the generator regulator so we know what you have for sure and your serial # to verify year

This is exactly the problem I am trying to figure out. Yes the tractor is a 1952. The serial number is 146,920.

What I am finding is over those 70 years parts have been exchanged. For example the hood is set up for long eared dash but the current dash is a short eared. This may be where the 4 way switch comes into play.

Regardless of what it once was I am trying to figure my path forward to make this a dependable functioning tractor based on what is on it now. Also I am trying to deal with the parts I already replaced without fully understanding the details (ie the light switch).

The unit does not have a cutoff relay unless they made them with 3 electric connection tabs on the side and a forth under it.

Consider a 12 volt single wire alternator.

Voltage regulators have a cutout relay. The purpose of a cutout relay is to disconnect the generator from the battery when the tractor is not running.
I have an excuse. CRS.

I have a battery tester that looks like this and It is my go-to device. it reads voltage and tests the battery and the charging system for both 6 and 12 volt systems

Did you replace the regulator? If so where did you get it? I have had 6 volt imported regulators DOA out of the box. NAPA has the VR851 but it is not designed with the rounded mount to mount on the generator. I think Brillam sells a regulator like that.

You should not need a hose clamp to mount the VR. There should be taped holes in the generator case. If there are no taped holes maybe you need to do the plate mount for the VR

I don’t have a battery tester like that but do have a couple digital multimeters. So far I haven’t done any testing as I am trying to understand what I have before I start testing.

The voltage regulator was on the tractor when I purchased it.

It's also possible that someone in the past changed the bolster and kept the SN so that you appear to have a 52 but it might be older or newer. A cross check of the major casting codes might reveal that it contains parts from different years of manufacture. JMHO

Yes I have already checked the casting codes and part numbers for the clutch housing/tube, final drives, right extension tube for rear axle. Everything seems correct for that year and serial number range. At least was correct. I have had to replace some of the cast parts.

Maybe I need to focus my question.
1. Is the Delco 1100501 generator designed for a voltage regulator instead of a cut out relay?
2. Is the correct location of the voltage regulator below the generator on a mounting plate? Tm sells that plate but it seems pretty simple

I found this post very helpful before I got my tester http://www.farmallcub.com/phpBB2/viewtopic.php?t=38133

It walks you through testing the system with a digital meter

that is a regulator someone clamped to the generator, so follow the wiring diagram for a regulator system to verify its wired correctly to start with, then just follow this flow chart to help find the issue with it not charging, regulator should be mounted for good grounding, hose clamp does not cut it

my 49-53 cubs have a bracket http://www.tmtractor.com/new/el/952fp.htm.

AS TST wrote you need a good ground for the regulator. you may want to try a ground wire from the VR mounting bracket to a good ground and see if it starts charging.
