Stator and Trigger test on 86' 35 hp Merc?

[aMeyers11]

Hi everyone, I'm trying to test the stator and trigger using a multimeter. Via a manual and online resources I've found that the specs are:

STATOR:
Black yellow(LS) to ground=3200-3800 ohms
Black white(HS) to ground=225-300 ohm

TRIGGER:
Brown yellow to brown white=750-1400 ohms

Problem is, there are many of these colored wires and it has me very, very confused. Im not sure which black and yellow wire to test between ground and I'm not sure how to disconnect the white and black wire from the switch box for testing? All black and yellow connections get nothing except for the very top right connection is about 0-10 ohms between ground. What would be a good ground point? I havent tested the black and white wire becuase I'm not sure how to disconnect it. As far as the trigger goes I'm unsure of which brown yellow and brown white pair to test between, becuase there are 2 of each color wire on the right side of the box. I'm sorry if this is all confusing or stupid questions, any help would be very appreciated. I will post pics below. Thanks

Here is a wiring diagram, but it doesnt seem to line up with what I have completely though

Does anyone know if there is a trick to disconnecting wires at the switch box? I've got 2 of them apart but the rest just wont budge? Any tips would be greatly appreciated. Thank you

Here -- hope this photo clarifies the following:

Trace the wire bundles from the rotor and trigger to the switch box.

Lift the necessary wires off of the box and separate them at the connectors there.
\
Then test the trigger side of those wires and the rotor side of those wires.

Use a bolt that goes into the crankcase as your ground.

If you get zero ohms on any reading, either the wiring, connector, or the part itself is open (bad). You will have test further to figure out which. Those connectors look green from corrosion -- which is why they are hard to separate, and possibly aren't connecting (if you are getting a zero reading). Hope that helps.

That helps a ton, thank you so much! I'm always amazed how helpful everyone is, I really appreciate it!

Ooops.... I was typing too fast. STATOR, not "rotor" --- but seems you understood anyway!

Yeah that helps a ton, for some reason I wasnt thinking straight and I didnt realize there is actually 2 stators: the stator for ignition and then the charging stator that connects to the rectifier. Thanks again!

Alright so I tested both the leads on the ignition stator and i got no resistance reading from either to ground. I removed the stator and noticed that the bolts holding it in had some oxidation. Is it possible that it wasnt grounding to the powerhead due to this? Is there a way to test it with it off the power head to double check it's no good? Thanks
