Hi, It's Dan. I will be glad to help. If all your fuses, relays, and safety switches/wiring check out good the next step is to check your filter for metal/debris indicating an internal hydraulic component failure occurring. What is your serial number machine? Any warning indicators going off?

Customer: replied 1 year ago.
Hi Dan my serial number isJaf426477. And no there is no indicator going off. when I released the park brake button it used to charge my hyd but is not doing that now.

Hi Tim, Are the controls locked out completely? Have you swapped relays with a known good one to confirm they are good? What are the chain of events when this occured?

Customer: replied 1 year ago.
changed all relays Dan it worked great for a couple off minutes then blue again. could you recomendme were to get a wiring harness foe that machine
Expert:  Dan replied 1 year ago.

Hi Tim. thanks for the update. Check the connector pins in the harness for any shorted or burnt connections and the harness where it runs through any clamps or along the frame. Sometimes they can rub through and if you find an area like that that might be shorting you could repair that area. Clean and check all your grounds too as a bad ground could cause similar symptoms if the harness checks good. Here is the dealer locator link.

You can also google some equipment salvage places and put parts on a locator if you decide to go with good used.
