Kubota B3350 cranks no start no fuel

[Hsaydah]

Hello everyone, first day on the forum, we have a 2016 kubota B3350 we are having trouble with.
my father was using it to grade some flat land, on a reverse pass he had stalled out, tractor died and would not restart. There is no display on instrument panel but the glow head and battery lights come on when key is turned. I tried jumping the starter solenoid, engine cranks but doesn’t turn over, no fuel and no display on instrument panel.
I have tested all of the fuses and they all checked out good. Safety switches are all good, I have also checked the key switch and it’s good. I’m thinking the fuel solenoid isn’t opening. But obviously I’m having a different problem with the instrument panel not lighting up. Any ideas fellas?

Check the PTO lever - I have had this happen more than ONCE .... A little bump here and there ........ and you have a dead stick!!

Push/Pull on PTO lever (assuming that is how it is engaged) and see if that makes a difference

Focus on the key symptom. No power to the display.
Fix that and the other symptoms will resolve.

Since the tractor was operating in reverse, suspect something got snagged and unplugged or ripped off.
An owner of a L3901 had similar but not identical symptoms.
I suggested getting under his tractor with a big bright flashlight.
He found this safety switch with its wires ripped off.

Look for unplugged connectors.

How are you checking fuses? Visually or remove and use a multi meter.

Is your tractor a B3350 or a B3350SU?

I am checking with a meter,
I have checked any ripped off wires, did not see any, everything looks good, he maintains this machine very meticulously,
It’s the b3350
I had replaced the pedal safety because it was giving hit or miss readings with the multi meter.

You must find why the display has no power!!!!!
A safety switch anywhere is not going to block power to the display.
I have provided two versions of the wiring diagram.
A jpg file below and a pdf which is attached.

I would decide which file format you can best work with. Print the diagram in two pages at the same scale so you can tape the two halves together so as to have a more readable diagram to study.

Above is how I study these complicated wiring diagrams using colored highlighters.

I see one 5 amp fuse feeding the instrument panel.

Of course a connector on the back of the meter panel could have come loose.
