    Cat 277B Aux hydraulic does not work

    It is worth trying, what makes things more difficult is that just before this issue started to happen cat had it replacing the hydraulic motors. I bet they had all sorts of connectors apart. Is the "J1" connector they are talking about the one one for the right joystick?

    Cat 277B Aux hydraulic does not work

    Yes I can do that as well as I am going to get my hands on another multimeter that is pretty new and see if results change. The joystick was new from cat bet I could bring it there as well and they would test it. Before that let me get a newer meter on it.

    Cat 277B Aux hydraulic does not work

    I just threw a different multimeter on it and turned the engine on with the parking brake on and rolling it forward i got about 20% always then not rolling it i got 50% and rolling it downward it went to zero every-time. Does this make any more sense?

    Cat 277B Aux hydraulic does not work

    I followed one of your threads regarding a skidsteer with hydraulic issues. I have a 2003 cat 277b. The machine is working well and the arms and all other hydraulics are working fine. The implement hydraulics however do not. they will intermittently work at best in one or both directions from...
