1988 Supra TS6M Comp - electrical system

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a 1988 TS6M comp.  I have no power anywhere in the boat when turning the ignition with the key.  The battery is fully charged.  I am able to jump the sellanoid and crank the engine so it appears power is reaching there and it also appears that the 40 amp breaker is ok.  There is a button next to the ignition key switch that when turned off disables all power.  Is there a master fuse somewhere in the boat or could the problem be with the ignition switch itself or the master power button next to the ignition key switch?  Help.

	I had a similar problem with my '89 Comp. I found that the 'circuit breaker' located on the back of the engine block appeared to be O.K.. I tested it by attaching both wires, incomming and outgoing, to one terminal post. The power was back on. I removed the breaker and attempted to replace it. I found available units online for about $150. But I played with the old one for a while and it seemed to loosen up. I put it back in and it now works fine. Good Luck.
