Solenoids (C, Fig. 487) for the high-flow option control are on the back of the control valve. Solenoid resistance should be 5.0-5.6 Ohms.
Charge pressure is used to control the following functions: • Solenoid (N) controls track tensioning • Solenoid (O) controls 2-speed travel operation • Solenoid (P) controls parking brake NOTE: The pilot valve manifold also houses the hydraulics temperature switch.
