Is this a tach connection point?

Attached is a picture of the back of my one-wire alternator on my tractor. Is the part with the black grommet a connection point for a tach?

The proof meter on the tractor is broke and has the wire cut.

If this is a connection point, the cables for sale on this site are on 30.5" long. It does not seem long enough to reach from the front of the tractor to the instrument panel.

NOT sure what you are contemplating, but that is an ELECTRICAL terminal (stator), and if I my powers of mind reading are at all accurate you are wondering if you can connect a MECHANICAl tach to it???
 
I am looking to install a new tach and do not know where to hook it up to. From posts and videos I have seen most people hook it up to the back of an alternator when the outlet was available.

Where would you typically connect a proof meter to?
 
My buddy has a kobelco excavator and it uses the alternator movement to prove it started. It's new enough I would bet the hour meter comes off of it too.
 
I am like Bob , I think you are working with a tack that has a cable drive. Those were driven off an end shaft adaptor . Used on a lot of AC tractors like the AC 185 , which I think used a delco so you might be able to work back to a one wire unit but think it would take a different center shaft .
 
If your alternator had a provision for a mechanical tach drive using the style of cables you mention, it would look like THIS:

Your post left a lot of questions unanswered. What kind of tractor is it? Do you Currently have a mechanical drive hour-meter? And are you
were trying to replace?. I?ll try to tell you my situation . I had a mechanical drive hour meter on one of my tractors that was broken and the cable
was broken too. It still had the mechanical drive generator. So I was able to purchase a new hourmeter and a new cable hook up to the back of
the generator and it?s working fine. On my other tractor the generator have been replaced with an alternator that does not Have a mechanical
drive outlet. So I had to replace that hour meter with an electric tachometer that runs with 12 V power and an impulse lead from the coil. that
tractor has a gasoline engine. If you have a diesel engine it does not have a coil , and you?ll have to get the impulse for the tachometer from the
back of the alternator.

My early 1980’s Deere Mannheim utility drives the taxh from the alternator .
 
Sorry about the late response. I have a 1963 Ford 2000 4cylinder gas tractor. I bought the tractor a month ago and slowly making changes to it. The existing proof meter is not connected to anything and has some sort of threaded connection on the back where I assume the cable went. I would like to buy a new proofmeter and do not know where to connect to or which cable to buy.

The previous owner installed the one wire alternator shown in the picture above.

Previous posts have pointed to a connection on the back of an alternator as a possible connection point. Are there other better places to attach?
