First I would like Thank Old Machinist for his prompt relay to my request for wiring schematics for my 743! Got it wired today and works like it should with switch glow plugs and switch right to start glow plugs. But now I have discovered another problem when I push down on the back of the boom/bucket hoist to raise it wants to draft down but as you put more pressure on the control it will go ahead and raise the boom/bucket as it should it kind of acts like it has air it system is this possible? Thanks for all of the help. This forum is so full of info.
