Can some please tell me were I might get a diagram of the wiring for a 1982 astroglass bass boat. The trouble I am having is there are 3 tilt and trim switches on the boat. At first they all worked the the one by the motor quit, now the one by the copit quit but the one in the front of the boat still works. I have replaced the two switches, but they still do not work. Any help would be helpful<br />Thanks nebtnman
