Glow plugs not working on Kubota Bx23s, 8 years old

[MikeCRose]

Out of nowhere my reliably starting (and seemingly new, where did that eight years go to?) Kubota BX23s wouldn't start, and we noticed the glow plug light wasn't coming on. First thing checked were fuses and it seemed one time that just removing and reinserting the fuse got it to come on and the tractor started. The next day, no dice on glow plugs again, and now the fuse thing doesn't do anything, so maybe that was just coincidence.

We're wondering if it's the module that controls all of this or could we be missing something simple? Thanks!

in the electrical subforum here, post #13 has the wiring diagram !!
In the upper rightish area there's a 'glow relay', that might be your problem.
It controls the high current going to the GPs as well as feeding the glow fuse that feeds the dash light.
There is a 'glow' fuse but is only powers the light on the dash.

There's 4 relays under the dash, by the fuses. they're all the same ( I think, same part number...)
