Jcb 532-120 front legs not working

[srh222]

Good evening

Our 2003 532-120 loadall front legs are not working, just randomly stopped, no squirm if you move the levers, feels like a stuck safety valve to me?
Any advice welcome please

Switch on the Dash has'nt been randomly turned on has it?

bad earth or coil gone down? or is it manual controls

Could be proximity switch on boom at back or that circuit (stops legs working when boom is up above certain angle). I assume 532 has this I know my 535 125 has and there's v little difference between these machines.

it does and most likely is this, it has three wires, you can cross them to check it..... but I can't remember the sequence

If you look in behind the cab between the boom and frame you might be able to see the sensor that picks up the boom angle. On ours it's behind the bit of steel plate cable tied on to allow us to operate the jack's with the boom up

Yours sounds very similar to mine

Hiya. I've got the same problem on mine now. Can anyone tell me what the cable sequences are to short the sensor out so I can test that?

Many thanks,

Jon

How old is the machine? Our latest one if you push the button on the SLI it lets you do more.

Sorry - only just seen this. Its a 2001. Not sure what 'SLI' stands for but I assume its some sort of electronic display. If that's right, I'm not sure this has any sophisticated electronics.

Safe Load Indicator ..... are you operating this ??

 

[jonnyt]

Well, 'yes' and 'no'. 'Yes' I will be using it - I have just just never heard the acronym before, one of the reasons I always teach my students to steer far away from TLAs. On the other hand 'no' because the front jack legs don't go down.

That was rather the purpose of my question - do you know the answer? Or does anyone else know the answer?

I should also say that the manual for this machine would suggest that the load indicator is in effect a standalone system and therefore not integrated into an electronics system which would impact on the operation of the jack legs?
