Tach / Cable Adjustment
Hey folks,
I just had my tach repaired and installed it in my console. I then hooked up my brand new tach cable to it and tested this before I installed it in my car.
When I loosely connect the cable to the tach, I can gently move the cable and the tach responds; however, when I tighten down the connection to the tach, I can no longer twist the cable making the tach spin.
It seems to me that the cable needs adjusted; however, I can't tell if the little "nut" on the cable is crimped on or not.
Any help is appreciated.

Suggested Bubba fix:
Add a large bore washer that will fit inside the 'nut' so it can be tightened finger tight.

I'll give it a shot. The same cable won't work on the speedo side either so I'm sure it an adjustment issue

When I had my speedometer rebuilt, the rebuilder told me that many of the repo cables were just a touch too long. The result of that, if I didn't check it and "adjust" the length was that the speedometer and the tach would wear out much faster because of the cable pressure on the gauge.Geek

It's best to check all the new cables carefully not only for proper length but also for turning resistance. I recently had a new Tach cable for the 64 that I could bearly turn by hand. It was NEW from one of the major vendors. I ended up having to disassemble the cable and enlarge the end opening holes to get a smooth operation.

Just for follow up, ended up ordering a new cable and it worked fine (previous one was bought over a year ago and vendor wouldn't replace it even though it was never used). The best I can tell is that the rubber casing was cut a little long inside and pressed against the tach. The new one looks a little shorter and operates very smoothly.
