753 no bucket or boom controle

phazer08 · Jan 7, 2015

I have a 753 G 2002 bob cat when I turn the key on it beeps three times and the ACS indicator lights up. The bucket indicator light wont light and the controllers wont unlocked. In either foot our hand control. I have a code 32-65 showing witch I believe means low or over voltage. I have gone over the wiring and found two spots that were rubbed through. I have fixed them. I have removed the hand controllers out of the unit and gone over all connections the only way to get the code to clear is unplug the computer controller. I believe the controller is what is not working, can I buy one ready to be installed or do I have to take the machine into a dealer and have it done there. It was a big job to remove the controller so I would like to get one ready to go in or at least buy one install it then take the machine in to get calibrated.

If it is the controller on Right Hand side (sitting in the seat), that controller can be replaced then calibrated either manually using the hand controls. It it is the controller on Left Hand Side, Main controller - that needs to be programed with serial number and other information read from the current controller before it can be used. A dealer has no way to program these out of the machine.

Thanks anyway I put it back together, was going to take it to a dealer so I moved the controller and went over a few more connections. When I started it all was well it is working fine now. Ran it for a couple hours plowing snow all is working.

Had a loose or slighlty corrodid connection in the 5 volt circuit so controller reading less than 4.75v.
