attachment arm wont connect

    my 7600 blizzard wont connect to the truck, by the attachment arm.
    after plugging in the wiring harness & using the side switch, the attachment arm wont go up and connect to the truck. (i have the switch in the proper position).

    When I tested if it moved left & right, it did.
    I tried raising the plow & it raised all the way.
    I looked underneath & to my surprise it was connected.
    I thought that the attachment arm should have been hanging there,, but It was actually connected to the truck.
    I worked it for the night and all was good.

    deciding to the remove the plow yesterday, the attachment arm did come off and release as normal (not from inside the truck)
    however it wont go back on unless im using the joystick in the truck to do so.

    I also hear the motor working while trying to connect, but the cylinder isnt moving.

    Any ideas?
    all hoses are good, fluid level is fine.

    1st: The plow needs to be plugged in with both plugs.
    2nd: The controller needs to be OFF for you to operate the switches on the plow.
    3rd: The front switch (plowing/off/arm) needs to be held backwards or towards the truck while moving the second switch.
    4th: The rear switch (up/neutral/down) needs to held up or down while holding the front switch.

    If nothing happens then most likely one of the switches is bad ... my guess is the rear switch (up/down). To diagnose without extra parts: Since you know that the front switch works in the "plowing" position (you can run the plow with the control), reverse the plug on the back of the front switch. This is much easier to do with the switch out but sometimes removing the switch damages it, so use your judgement. Switch the switch on like if you were "plowing". This gives you constant power to the back switch. If the arm works, the front switch is bad. If the arm still doesn't work, most likely the rear switch is bad.

    NOTE. You can always make the plow connect if the plow works from the controller. The "raise" function will move the arm up and pull the plow onto the truck.

    If you are working on a PH1 ... which I think you might be after rereading your post ... then this should help.

    hi guys
    thanks for all the suggestions.

    I was out looking this over and figured
    to try some terminal cleaner in the plug.

    I let that sit for a minute and put in some dielectric grease.

    it must have been a dirty terminal connection as it
    starting working.

    all is fine now.

    thanks again for the prompt replies and suggestions.
