I have a 2010 JCB 190T with about 1700 hours on it. I have been having troubles with it blowing a 15amp fuse for the park brake and loader lock which then leaves the machine immobile. I found two bare wires at the plug for the contact switch that runs the park brake on the left side console so i repaired that and bypassed the plug and switch to rule that out however it has blown that fuse a few times since. the machine is currently sitting partway out in the field to go feed livestock. I see there are numerous other wires in that harness that run up into the console and travel joystick and they are sort of squished in behind the pilot hoses. I am not sure if the issue is in that harness now? To check the wires the console and hoses will have to be pulled my the look of it. Just wondering if anybody has had any similar issues and may have something simple to check before i pull this all apart in the field? Im a bit nervous about dragging it down to my shop with the dozer and im not sure my excavator will lift it onto the trailer to take to the dealership. Any help greatly appreciated. Cheers, and Happy New Year!
i dont have that particular machine, but like you said, i'd check the wiring for any cuts, and perhaps a faulty solenoid, pulling too many amps. does the fuse blow right away? blow when the machine rocks around?
Its pretty random. Its done it a few times while operating and right now and a few other times it has one it on start up where we cant even get it to move. Other than the hinge point on the control lever all the wires are pretty well loomed and strapped. Sadly each wire is the same size yellow wire all in one harness so tracing them is difficult. And little to no room to do so without removing interior and cab. This things just parked off the edge of the field right now so not an ideal place to start that surgery mid snow storm. Trying to track down schematics that may show solenoids or something to help figure out a way to bypass the park for now to at least get it to the shop, but, everybody has taken a 4 day weekend up here
if i remember right on jcb, all the wires are yellow, but isnt there small writing on the wires?
