JCB 812 broke again

[Baloo]

hello

l am in need of some help if possible please, l have lost control of my 812 , it starts and runs fine you can track about ok but non of the joystick controlls work just as if you had the dead mans handle up,
l assume there is a 12v solinoid somewhere that the dead mans switch disconnects when operated ? dose anyone know where this is located ? l would like to try putting 12v straight to it ?
does anyone have a wiring diagram for an 812 or know where l can purchase a workshop manual

l have taken these pics of solinoids in the valve comparment, does anyone know what each one does ??

its all fixed, turned out to be nothing more than a loose connection on the starter,
just followed the "lack" of power back untill l found it, if l could find a wiring diagram
l think l would just rewire whats essential and throw the rest out

Here's the the early wiring, if you drop your serial number I'll fish out the correct one for you . Cheers Mark

hi Mark
thanks for that, l think mine must be a later one then as that wiring diagram dosent tally with what l have,
serial number is 203173
thanks again Andy

cheers Andy

Hi Mark

I've an 812 here that needs rewired fully since all the wires have been eaten by something you wouldn't have all the wiring diagrams for it as I'm struggling to find them anywhere and there's nothing on the machine to trace

Thanks
Michal
