Working on an 87 Force 125 .No tilt/trim. There are no relys for the tilt motor under the cover. The dash switch looks like it carries the load as there are 3 large gauge wires to the switch. A green for down, blue for up and a common. Should this supply +12vdc or does it supply the ground to complete the circuit? I checked it with a meter with ignition switch on and no voltage in any terminals. Am I missing something?
