Ammeter for '76 Cub

Postby Worksmart » Sat May 27, 2017 8:11 am

Working on my '76 and want to replace the ammeter. The number on the face is 536229 which is a good part number.

Unable to find an exact match as the replacements with that part number are marked 30-0-30. Alternators in parts catalog show 37 or 42 ampere. Brillman catalog shows a 60-0-60 and recommends this for alternator equipped tractors.

Unless someone can point me to a direct replacement, which should I use a 30-0-30 or 60-0-60 ammeter?

Thanks in advance,
Chuck

JMO, I prefer a lower scale like the 30-0-30 because the greater movement of the needle is easier to see when registering the same current flow.

I assume you still have the generator, thus 30 amp gauge. Alternator takes the 60 amp gauge.
I have an excuse. CRS.

Hi,
If the ammeter still works good, maybe you could replace the glass.
Here is a post about that, the new ammeter there is not like yours though.
I'm not sure how hard they are to take apart to replace the glass, or if the newer ones come apart. :)

That's what is a little confusing Eugene. The tractor is equipped with what appears to be the original alternator.

So the 30 amp gauge seems out of place. I guess I'll go with the 60 amp gauge. Brillman has a nice one with the IH logo.

I saw that thread Glen, thanks.

Hi,
Good pic of the alternator. It looks like the IH Delco alternator. They started using them at Cub serial number 248125, the Cub parts manual says. I tried posting the page, but it wouldn't work.
You can look on the alt and see the output, it should be stamped in the metal, on the bottom side. It is near the mounting bolt on the curved surface. It says 37A, or 42A, etc. Whichever the output is. :)

your pic is the correct factory amp gauge with an alternator, it was changed to that when the alternator came out
