I have a cat 277B that when you turn the key on all lights light up as normal and once it starts all lights go off except for the implement lockout. And nothing works and it will not track and nothing change when you hit the hydraulic button or raise the lap bar. Any ideas? Thanks
The serial number is bhmdh02033
Are you sure that the lap bar switch is working - in other words has it been tested with a DMM to ensure that it opens and closes correctly.? Does the machine have a cab.? If yes, is the door switch working correctly, if no are the contacts on the door switch bypass harness good.? Do you have the capability to test electrics.? If so I can send you the electrical schematic.
Yes it has a cab and the door sensor has been wire closed for years. The lap bar and seat sensor is working because it won’t start without the lap bar and place. I wood love to have that electrical schematic if you have it. Thanks you
