Cat 287c no crank from the key. All lights come on. Exclamation mark Flashing. Jump solenoid off and machine started, machine will travel with left joystick but no bucket movement with right joy stick. Trying to find out what interlocks is in the starting circuit. *CAT0287CTMAS00835*

Thinking about it there aren't any. The interlocks are the arm bar and the seat pressure switch (if equipped) for the hystat drive system. Then you have the door switch which is the interlock for the implement hydraulic system. So nothing should prevent the engine starting on the key. Moving the machine or operating the implements is a different story.........
