My tach stopped working in my 7020. I think the tach is bad. No longer available through AGCO, part number 70262237. Anyone have a lead on an aftermarket source? Dealer said he could get one for a 6080 but the part number was different. Any idea if it would work?

Thanks

Joe

Contact Star Speedometer. He rebuilt my 185 tack this spring and was able to keep the hours. It looks and works great.

It runs off a pulse from the alternator. I would check that before buying one. The plug in on the side of the alternator that has 3 wires, it is the offset one for lack of a better term.
