What age of 130?

Does it have the looney unlock procedure dreamt up by an engineer afraid of their own shadow? Or does it normally just start with a press of the button?

Can you hear the solenoid beside the pto shaft clicking to engage the clutch?

What's the mudguard button doing? Will it start off this?

Normally starts at press of button, 05 year, mudguard button doing same can't hear clicking from solenoid but never have, only just worked out where they are, just heading with tester to see if power going to solenoid!

Sure you would notice if the auto switch is on, once had this issue with a driver.

Nope checked that! Just checked two solenoid next to each other one on left has a constant 2.9 volts going to plug other has constant 0.05 volts which jumps to 0.1 volts when button pressed???? Presume should be around 12 volts when button pressed??

You can swap the diff lock and pto wiring around to check if its the solenoid or the wiring . Ie swap plugs and use diff lock button to work pto .

Which is diff lock solenoid don't have workshop manual here so not sure what's what!

There's two solenoids side by side down next to the pto stub. Swap the wiring plugs from one to the other as @LiamO suggests, then use the diff lock button to see if the pto starts.

If it does then it's a wiring problem.

I think the front diff will be locked though, so its not a permanent solution?

PTO is the one on the right of the two as described above by DrDunc .

Offending item!!! Would have been much easier to find had manual made some reference to fact it had a relation to pto only noticed by chance when scouring wiring diagrams in workshop manual that arrived tonight that RL1 was part of pto circuit! Big thanks to @LiamO and @DrDunc for showing us quick way to show solenoid was working and fault was in wiring/switches. thank you!!

Glad you got it sorted easily.

I can't view the attachment for some reason, but I presume it was the switch relay inside the fuse box (RL1?) that was at fault?

Yes relay rl1 was dodgy

Right, we are back here with the same problem again this time it is not the relay that gave problem last time, using advise given before solenoid is working fine(swapped wires with diff lock works perfect) presuming have dodgy wiring as not getting power to plug at solenoid. Anyone had similar and know any likely spots to check first or how wiring is laid out?

Fuse?

 

[dazza b]

Or button on mudgaurd gone faulty?

 

[Komatsu]

Fuse is good, mudguard button doing same as cab button ?

 

[LiamO]

Try disconnecting both switchs separately. I have had one faulty before

Will try that tonight when get home, if one switch is disconnected then other one should work, provided everything else is ok?
