    HI
    Does any one know exactly where the earth points are for the PVC and and EC on an EX100 - 2?
    I have a bad earth somewhere, but am struggling to find it. My digger goes to full swash without warning, and without any form of timetable. I know there is nothing wrong with any part of the system, because some days it digs all day without problem, or another it stops 10 mins or 2 mins into the day. Pumps motors etc all check out 100%. removal of both pump solenoid fuses, allows normal digging......gently... so no hot oil!!!
