JCB 3CX Won't Start. Auxiliary Hydraulic Fault

[Mattie]

Hi,
I have a 2007 JCB 3CX which wont start. The fuse in slot A1 is the Auxiliary Hydraulics fuse. Everytime I turn they key this fuse blows and cause the JCB to not start. Can anyone shed any light on what the problem may be? Could it be the Hydraulic Pump?
All help appreciated;
Thanks!

Aux hydraulics sound like 3rd service or hammer lines, there's an electrical fault on the line causing the fuse to blow. Is it electronic control of 4in1, roller switch (if jcb did such a thing).

Are you reading the fuse diagram right? cause a fuse for aux hyds shouldnt have anything to do with starting? Logically anyway but I guess this is a JCB so anything's possible!

Turn the key to the ON position or the Start position?

If start position:
Check fuse size with book/diagram, just big enough is best, so if it says 20A fit a 20A. But you might have too small fitted?
Pull any relays labelled start, see can you get the fuse to stop blowing.
Take the little control wire off the starter solenoid, it just pushes on.
See if the fuse still blows, if not you need a solenoid.

JCB wouldn't be the first to have a printing error! or put a sticker the wrong way up!
