I have a '83 V6 150 Black Max serial number 6312908. Should the black-Yellow kill wires that connect to each switch box show any voltage to ground when the key is in the "run" position. Key off I get 0 volts. Key on (motor not running, switch boxes out) I get 0.2-0.4 sporadically. Sometimes it 0.02 volts when exercising the key.
