Hello All-
Ok, myself and mechanics are frustrated as can be! This problem has been posted before, and there have been a few solutions suggested, but we are still not fixed! I'll try to outline the problem:
- When you drop the 'dead man lever' (not sure if that's what it's actually called, but don't know what else to call it!), the 'lock' on the display would stay lit up, and there would be no hydraulics at all This has been an intermittent problem since I have had the machine, approx. 10 years. Very sporadic when it would happen. Sometimes the 'lock' would disappear in a few minutes and I am good to go, sometimes not for 15 minutes, sometimes, like right now, it will not unlock at all!
- We have tested solenoids, changed relays, checked ground wires and changed the pilot filter. No luck! When we switched one relay, the 'lock' now disappears on the display, but still no controls.
- Now, by total chance, we find that when machine is in 'fine' mode, everything works!! And, the dead man lever is not even down. What on earth could be causing this?
Our next step is to find a wiring schematic to try and isolate where a wire may been broke. Does anyone have a wire schematic, or know where I can find one?
We are desperate!! Any help or advice at all would be much appreciated!
Thanks in advance....
