I'm looking at a 753 and I'm wondering if the auxiliary circuit works. All that is with the machine is the bucket so I can't really fully test it out, but when I activate the remote circuit (Yes those lights do light up) and press the buttons on the right control stick I don't hear any different noise. I would assume that I should be hearing the engine load down and oil being bypassed over the relief valve. Is this normal?
At my 763 when i am pressing and holding the auxiliary hydraulics button, the engine is shutting down.
If you are activating the auxiliaries you should definitely notice the engine bog down. If it doesn't change then something is amiss
