Kubota won't start

[Beccat1]

Sure hope someone can set me on course! Bx2200 had no lights, glow plugs - checked ignition switch, looks good. 30 amp fuse which sticks out by the oil filter was open. Changed that, had all panel lights and glow plugs - turned key on to start and it did but then died. 30A fuse blew again. Noticed a blue wire broke from it's connector, attached to a lug on a component that may be the oil pressure switch. Any idea if that component is the oil pressure switch?

I will fix that tomorrow and pick up a couple fuses but don't want to keep blowing fuses.

I also found a loose nut touching a bar with a black/red wire attached to it and it looks like that nut did arch to the bar a bit.

Any ideas?

30amp fuse was blown because the repair shop left a nut loose that was laying against the glow plug bar and chassis. While looking around also found a wire broke off the oil sending unit.

Fixed for $7, of course I didn't look for why the fuse blew before I replaced it the 1st time.
