Just like that. Thank you very much. Any thoughts on why my speedo isn't working? I understand the premise behind how it is supposed to work but I can't find any way to test that the speedo cable is doing its job.
Should probably be a new thread so people can find it. What I found in my 65 Newport was that the bore had worn so much that the spinning magnet wobbled and caught the aluminum cup that carries the needle. Fortunately, the cup twisted but didn't break, so I was able to salvage it. The cable broke.
Since it broke at the gage, I was able to pull it out and feed a replacement down. You can feel when the square tip engages at the tranny end because it won't spin anymore. Cut it to length (one chance), put the square tip on and crimp it using the tool in the kit w/ pliers, then lube the cable w/ the special lube (oil & graphite) you can buy at most auto parts.
However, you must fix the wobbling magnet or your cup will break next time. I tried adding a bronze bushing, but without the tools gave up. I sent just the small magnet assembly to a speedometer shop in Bakerfield and they fixed it better than new, because original was a steel shaft spinning in an aluminum hole and the bronze bushing is oil-impregnated. I haven't seen a wobble since. Pre-internet days (>15 yrs ago), so easier today to find a place.
If you see your speedometer needle starts pulsing at low speed, better fix the magnet soon. That started in my 82 Aries and I found an even worse design. The spinning magnet was held in a plastic cup that had cracked. I wrapped sewing thread around the cup and used plastic epoxy. Fixed it and held many years until I junked the car since a blown head gasket and failed paint. Later cars dropped the analog spinning magnet for electronic sensors (mid-90's?). Great, but when those dashes fail, major expense.
To test your cable, the easiest way is to disconnect at the dash an place where you can see the end while you drive slowly. Hold it slightly to insure it turns against resistance. Easier than disconnecting the transmission end (most cars).
