Same issue here. Lift the arms and the slowly start falling. No external leaks. The arms do not fall if I raise them and lift the lap bar (or turn off the hydraulics). Only leaks down. If I tilt the bucket and lift the front off the ground, it holds just fine.
Just to close this out (sorry for the delay)- Dealer replaced the controlled for only a little over $2k :) It was definitely the issue. I would have sent it off for repair, but it is epoxy filled and the repair would have been a "maybe". So I made the dealer give me back the bad controller...
My problem is, I don't actually have an overvoltage condition. The controller thinks it is an overvoltage, but it is within normal limits when measured with a meter.
My thoughts too. Pretty sure its going to be wherever the system voltage is measured. I am just not sure if it is measured in the controller or somewhere else.
OK fellas, I got a real head scratcher going on with my S185. I get an occasional 41-10 and 3-10 error, both indicate an over voltage condition. I have the keypad and deluxe display, so I can monitor the voltage through the "Vitals" on the display. The voltage is reading about 1.5 volts high...
