Hey guys and gals, I have a friends new holland lb75.b that the ac is not working on. I don't have a manuel for it for one. Two I have tried to trouble shoot it and can not get a signal voltage to the compressor. I can hot wire the clutch and it works the refregerant is a little low around fiftheen pounds. all fueses seem good. If anyone knows which fues is the ac could you pass it along to me? Its a really low hour machine with only 634 hrs. What I am thinking of doing next is putting more gas in it, so the thing isn't shutting it down do to low pressure.
