My friend Charles removed the ignition switch and all wiring at the helm to refinish the woodwork.
Looks beautiful except - now it won't start.
Charles said he made a wiring diagram and put it back together the exact same way. I have my doubts, I found two loose connections, never a good sign.
The ignition switch has five wires and six terminals.
Here's what I found.
Wires (I traced them out):
Red - from Battery (+)
Ignition switch (the way he re wired it):
What are the M terminals for ?

Don't know what is your motor.
But in reference section, there is valuable information.
Have a look http://continuouswave.com/whaler/reference/wireColorCode.html

Does it turn over, but not start, or not turn over at all?
And I suspect Purple should go to I, not Choke. Purple is

It is impossible to tell how your boat is wired. The diagram shows a typical OMC installation. The color of a wire's insulation does not always reflect its use. Some installers may use whatever wire they have on hand, and not follow the color code guidelines presented in the REFERENCE article.
A motor has to be supplied with +12-volts on its ignition lead. This is normally a VIOLET conductor and is attached to the A (or I) terminal of the ignition switch. If this wire were omitted a motor would not start, even if it was cranking.

Dera Chuck, jimh,
The engine does not turn over, but it did when Charles bought her. Charles removed wiring from the helm and did some re-wiring, the running lights, helm light didn't work when he bought it. So he removed some wiring and ran a seperate cable from the battery to feed the lights.

The engine cranking circuit is about as simple as electricity gets: a battery, a switch, and a solenoid coil. You hook the battery to the switch, and when you turn the key the switch supplies voltage to the solenoid.
