Basically, I have a 1993 Mercury 60HP 2 stroke twin carb 3 cylinder outboard (serial number is OC161680) with issues (see http://forums.iboats.com/showthread.php?p=2398807#post2398807 for more details). It has been suggested that I check the resistance of the stator, and I'm slightly confused on how to do this.
From my reading, the resistance should be:
Trigger Ohms - 750 -1400 Ohms.
Charge Coil Ohms - High Speed - 28 -32 Ohms.
Charge Coil Ohms - Low Speed - 500 - 600 Ohms.
Now, with testing the Trigger, I understand that, disconnect the lines from the CDI Switchbox, test the following:
White/black (white/black) to Purple, White and Brown, and the result from those 3 should be in the 750 - 1400 Ohms range.
But, how do I test the stator/charge coil? What is the go with the high and low speed resistances?
Here is a wiring diagram of my setup:
So the wires off the stator are: blue, red, and two yellow/reds. Where/what do I test and which is the high and low speed?
