Have a 1989 Merc 90 T/T unit. 3 wires present, black-blue-green. Looking for a way to test unit. Is black ground and green/blue + for trim and tilt? Thanks!
Fouled plug.....<br /><br />most reversable dc motors fall into these two styles. an ohm-meter will tell you which one you have. REMEMBER!! if you connect 12v directly across the armature, or directly across the fields by accident.........smoke!<br /><br />Good luck man...<br /><br />
