Original volt meter
 

What's the correct placement for a voltmeter on an original?

Did they even make one? I've certainly never seen one on an O. Don't recall seeing anything of it in any of the manuals either, but I could be wrong.

They did make a charge indicator (ammeter) with a bracket to mount it.

Very interesting! I looked through all 3 manuals for it but there seems to be no recognition of it anywhere, not even in the electrical system diagram.

All I managed to find was this image, but don't that look like an hour meter??

Then I found this dash for sale, but that 2nd hole looks like a PO mod spot for an ammeter. You can still see the corner of the IH logo that woulda been there

Guess it isn't a very common feature

Yes, that is a hobbs hour meter in the pix.
Back in those days, not a lot of bells and whistles were available.
But I defect to those that are more familiar with the originals.
If they did have a charge indicator it would be an ammeter, not a volt meter
as was the norm back in the day

The only device available "at that time", was a Ammeter as an accessory.

it's right there in the parts book and the instruction sheet that came with it indicated the left side of the tower IIRC

I have a picture but for some reason It will not upload.

it's right there in the parts book Part #394 538 R9
And I believe the instruction sheet that came with it indicated the left side of the tower IIRC

Thanks for the help
