Re: 85h johnson hydroelectric shift schematic needed
Tag sure says '72 85hp. The plug sounds wierd, though. On all the V4s, 1969-72, it should be 10-pin, round, and about 1" in diameter, 3 big pins, 7 little. We're talking about a plug under the motor cover, right? <br /><br />Is the center of the prop hollow, so that the exhaust passes through it?<br /><br />OMC used many of the same wire colors around that era, so here is the color/function breakdown for the 1972 85hp. Since we have this wierd plug, take all this with a grain of salt & double check against what you see wires going to & what you're getting on your volt-ohm meter when you try different things. Given the costs of replacement pulsepacks, rectifiers, stators, etc. you really ought to find a wiring diagram, but if you're going ahead anyway...<br /><br /> black - ground<br /> tan - hot horn. This'll be 12V live 'open circuit' across the plug when the ignition's on. The temp sensor grounds to the block when the motor gets too hot, completing the circuit & sounding the horn.<br /> white - juice to solenoid<br /> dk green - live for neutral <br /> dk blue - live for reverse (Apply 12V to both blue and green to get reverse, just green for neutral, no voltage gives you forward. If you're motor is actually earlier than 1969, these'll be different & the no-voltage state is neutral.)<br /> purple/white - choke, terminal 12 on motor strip<br /> purple/green - terminal 10 on strip, leads to diodes then stator<br /> purple - term 6, leads to red lead on rectifier<br /> red/purple - 20 amp inline fuse, then on to the fat red terminal on the solenoid<br /> gray = tach lead.<br /><br />I don't have a brown or a blue/purple.
