2001 New Holland Dozer DC70 LCP, my dozer had been running perfectly fine, I tried replacing the engine temperature gauge, and my dozers blade stopped working and the tracks won’t move. I messed with some of the wires in the dash and a switch on the right side panel and the blade will work for a little bit and all my gauges work but still not the tracks. HELP!
I don't have any experience with New Hollands, but from your description, the two do not sound related. I'd check for a blown fuse or relay. Could be that something shorted or you lost a ground when messing with the gauge.
