I am the new owner of a traditional cutter
from the late seventy's. as one would expect she has fittings and wiring
remnants for various iterations of electronics
Three of the four sockets in the cockpit
I have identified, the fourth has me stumped. It is a round socket with an attached rubber cover . There are eight small holes spaced in a circle and a ninth in the middle. In the back there is a pair (red and black) attached that are presumably positive and negative 12 V. In addition there is one small black and one larger black wires .The fitting matches neither of the derelict tiller pilots left on the boat.
familiar to anyone ?
