Tach on a 2955

okierob · Jan 6, 2013

Noticed my tachometer quit working the other day on a 1991 JD2955.

I pulled all the covers off the dash(sound guard) and checked all the fuses i could find. That would be the 3 on the relays and the strip under the instrument panel cover.

Could not find anything wrong.

What gives the sidnal to the tach? I

Sensor in the front of the timing cover, output voltage can be checked but will have to look up the expected reading in Service Advisor. There is a multi plug connector at the bulkhead which can give connection truobles, and another connector behind the alternator.

thanks, i pluged in the alternator and it works, so i figure the sensor is shot. just did a quick test on the alt, did'nt leave it pluged in.
