I have a 5055E that will not start. I replaced the battery I replaced the starter relay. The gauges instrument lights do not work.
Are there more fuses other than the ones in the fuse box under the steering wheel?
I have a 5065E, and should be similar.
Raise the hood, on right side of tractor, above the starter and above the fuel filter, mine has a Fusible Link, kind of like what the kids use to fuse the big amplifiers in the boom boom systems in their vehicles.
Check for voltage on both sides of that fuse.
