With a brand new battery and clean ground and positive connections the dash light will not come on every time. When it does it seems dim or weak and sometimes brightens up some. The horn etc. will work when the dash light is on, not when it is off. When it is on and I try to start it nothing will happen and the light is then out for awhile. On a rare occasion it will click a bit like a dead battery but only for a partial second. I have tapped on the starter and moved the tractor with another just a couple of inches with no better luck.
If I ultimately cannot get it going I will have to have someone out or winch it up on a trailer.
