Glow plug light won't turn off, why?

[Outoftheblue]

After starting my tractor, the glow plug light just won’t go off. Does anyone have any idea what could be causing this or how to resolve it?

I had the same issue with my tractor before. it turned out to be a wiring issue. you can check the wiring harness. see if there are any loose, corroded, or damaged connections, especially around the ignition switch and the glow plug system

@Outoftheblue yo also need to check the glow plug relay and controller, they're located near the engine and air intake. check for any signs of damage, corrosion, or loose connections

Good call those connections can cause headaches if they’re not checked.
