Violet, orange, black from the icm feed the dizzy.
Green feeds the coil.
The coil gets power from a resister wire tied into the red feeding the icm, mine is a 1.35 resister wire.
So the coil has red to positive, green to negative on the coil.
Or red with a tracer?
Disconnect the wires from your coil, check ohms with clip on +, the other on -, my coil should read 1.13 to 1.23 ohms at 75 degrees air temp.
Then test center tower of coil to either the +/-, my ohms should be 7,700 to 9,300.
If either is off, coil is bad.
Also like i said you can ground main coil lead to block, if it sparks, coil works.
