Case 75c going dead after cold start attempt

[ego260]

I have a 2023 Case 75c. It’s in Wisconsin and it’s been very cold. When I go to start the tractor I run the glow plugs 3-4 times, then crank the tractor. It usually won’t start on the first crank, and the whole tractor, dash included goes dead. I have to reset the tractor by disconnecting and reconnecting the negative battery terminal and trying to start again. The tractor will eventually start, but what could be causing this and how do I trouble shoot it?

Could be a bad battery. Bring it some where to have it tested.

Bad Battery? Maybe, but it sounds more like bad battery CONNECTION. A bad battery doesn't temporarily heal when a cable comes off and goes back on. Disassemble, clean, and inspect all four battery cable connections before replacing anything.

I would bet money that you have a bad connection. Probably the negative battery cable to the frame. Just because it is tight don't assume it is good. Your symptom of everything going dead is a classic example of a bad connection. You should take off the negative cable and clean both the cable lug and the frame until they are bright. You should also make sure the negative battery connection is good. This means cleaning the battery post and the inside of the clamp on the end of the negative cable until the metal is bright. While you're at it do the same to the positive cable. Also feel the battery cables near the battery. If the cables feel soft near the battery but hard away from the battery then the cable is probably corroded inside. Finally, after the next failed starting attempt feel the battery cables. If one is hot, especially near the battery, this indicates a high resistance situation, most likely from internal corrosion. Check the positive first.
