instaling motor on newer boat. need wire question answered

[zell66]

Hello all I need help wiring my ignition syastem up to my motor. On the motor on the pass. side I have a bar with the following wires attached.

From top to bottom as follows:

1. Nothing
2. Yellow
3. purple
4. Black w/ yellow strip & red
5. green
6. orange
7. red

On the ignition side of the wires i have to hook up to this line are as follows:

purple, blue, white, red, orange, yellow, black and green

Now I assume I match color to color, but that leaves out the blue and white wire.

I do have pictures but do not know how to load them, Need help.

Happy to help. What motor is this? the type helps. I know mercruisers... so verify - verify - verify

Typically you match color to color.

purple, blue, white, red, orange, yellow, black and green

Purple = Ignition
Blue = Typically cabin lights
Black = negative return / ground
Red = positive (normally direct to positive) (if purple striped, Mercruisers go through fuse)
Orange = on mercruisers is the alternator charging circuit, but normally not remote from motor.
Yellow (on mercs yellow/red) = Starting circuit
Green/White-- no advice. Green typically implies a bond from negative (-) to boat hull (don't use hull as a wire)

They are not perfectly common across all motor manufacturers, so let us know what you have.

part 2 of this story is that when i was bringing boat back in and getting ready to load on trailer, I turned ignition key to off poss. and motor kept running! Had to pinch fuel line to get motor to quit. Must have something wired wrong...any ideas?

with some of the outboards there are magneto's instead of a powered coil. With an ignition coil, if you take the 12v away from the coil, the spark stops, with the magneto, you have to ground it out to make them stop. likely one of the wires (Black/yel/red maybe?) is the ground out, that would need to be connected to ground when the key is off. Since this is an outboard, Some of the wire colors above may be correct, but I would not use them without research...

I would ask that question in the Outboard forum, you will likely get the right answer, those guys know there stuff..
