The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
1990 johnson 120 hp--the maunual only shows 3 wires going to ignition--there is 7 i disconnected from old ignition--purple, purple/white, 2 black, yellow/red, black/yellow, red/white
One black should go to control case ground and the other black to one of the "M" terminal of the switch. The black w/yellow stripe goes to the other "M" terminal.<br /><br />Yellow w/red stripe to the "S" terminal. Start or solenoid.<br /><br />Purple w/white stripe to the "C" terminal...choke.<br /><br />Purple wire goes to the "A" terminal. Ignition terminal....feeds accessories.<br /><br />Red w/white stripe goes to the "B" terminal. Battery.
The control box case ground is simply a place to connect grounds....instead of putting all grounds on the ignition switch terminal. Usually, one "M" terminal is a "post" with a screw. The Black w/yellow stripe would go here but it really dosen't matter to which "M" terminal you use. Just keep the black w/yellow stripe by itself on an "M" terminal. The black w/yellow stripe grounds out the power pack to stop the engine. So don't put it with a black (ground) wire.
