’92 TRX300 Sensor Line Test

I’ve been pulling wires for the past week trying to figure out where the fire in this quad went. I’ve been through the test procedures per the manual and now pulling my last few hairs out. Ohm meter says good pulse gen., coil, plug wire,stop switch, neutral/rev., fuses, battery ground, diode, 12v to CDI, 12.8v-13.2v in battery, and the one test that has me stumped… When I tried the AC sensor line test, I have continuity Y/W to 3P Y alt. wire and also have continuity Y/W to G on the CDI .?. When I disconnect 3P connector, I have no continuity between Y/W and G at cdi. When testing the 3P Y wires to ground, I have NO continuity. Obviously, I’m tired and confused. Could you all tell me what I’m overlooking with this test ? Thanks in advance for any clues here.
