issue with the aba test

[TheDon]

well, apparently my spedo sucks. It doesn't like to register any form of speed under 25 mph, under that is bounces around and just acts stupid. This is in a 1985 Mercedes 300D.. I must have an issue with the spedo cable. Anyways, I'll see about borrowing a GPS and do it with that.

How hard would it be to find a new cable? Sounds like something worth having,

easy to buy new, for like $121.00. The speed registers fine over 25 mph,I've verified with those speed display boxes the police put out. It's somewhat of a common issue just like all of the other common issues in my car. I probably could just lubricate the cable since that has probably never been done
