I bought a nice 7753, but the boom wont lift. Along with that some bozo removed everythin related to the lap bar sensor so that's not functional either! So, as I see this, I have a couple of options - Go to the expense of buying all the parts, or just throw a hotwire on a couple solenoids and be done with it! I picked #2!!! But can someone tell me which solenoid t attack? As I understand, the lap bar sensor throws power to the left/side control vave, then the de direction is controlled by the right/side valve? So, do I have to hotwire the solenoids on BOTH valves or just the one on the right side of the machine? HELP!! I want to get this thing going!
