I recently bought a 5055E 4wd. 2010 model with the old style gauges. Last time I got it out the tach didn't work. Figured it was a loose wire so I took it apart and tightened or felt of all the plugs and wires. Also checked the battery ground - it was clean and very tight from battery to tractor frame. I also ran a ground wire from the battery to what I "think" is the ground on the tach and it didn't help. Also made sure all the screws were tight on back of gauge cluster. Help please. What's wrong with my tractor.
Also if anyone has a wiring diagram for my model I would greatly appreciate it.
