j. M1089 Underlift. The electrical portion of the M1089 Underlift consists of a remote control box (1, Figure 1-23) and

solenoids attached to the function valves in the WRECKER CONTROL PANEL (2). When the operator selects an

underlift function from the remote control box, electrical current is sent to the solenoid which controls the selected

function. The solenoid is energized and hydraulic pressure is supplied to the selected component(s). When the solenoid

is de-energized, hydraulic pressure is removed and the selected function stops.
