Stator Test Results + Burnt Wire - Need Some Advice?

OK. So I've been having trouble getting my 1987 Mercury Classic Fifty 45 HP Motor to throttle-up past 3000 RPM's. Was running fine, then bogged down and died at WOT. Had the RPM problem ever since. Just bogs down at 3,000 RPM's and won't plane out or really do much of anything. Think I've identified the problem as being a fuel problem or electrical issue. I have a good multimeter, so I thought I'd test the electrical system first (mainly stator). While testing the results, I also found a corroded and crumbled wire (white/black) coming from my ignition trigger. I have added links to show you guys that wire at the bottom of this post. However, I need some help deciphering these resistance results. Here goes:

Stator Test:
? Rx1 - (+)yellow to (-)yellow: resistance less than 1 ohm (good)

? Rx1 - (+)yellow to (-)engine ground: no reading (good)

SO FAR SO GOOD - HERE COMES THE TROUBLE

? Rx1000 - (+)Blue to (-)Blue/White: resistance =15 (should be in the range of 5.7 - 8.0)

? Rx1 - (+)red to (-)red/white: resistance =180 (should be in the range of 56-76)

? Rx1000 - (+)Blue to (-)Powerhead Ground: No Reading (good)

? Rx1000 - (+)Red to (-)Powerhead Ground: No Reading (good)

Rectifier Test:
All tests were good. Rx1000 - All continuity was where it was supposed to be reading at 16 and 11 ohms. No continuity was also where it was supposed to be.

Now, based on those Stator readings...am I in need of a new Stator? The White/Black wire coming from my trigger that is corroded, could that be throwing off my ohm readings from my stator? What is the purpose of that white/black wire from the trigger, and can it be fixed without replacing the whole trigger. Here are the pictures of that white/black wire:

If someone out there could help me navigate these problems, I would sure appreciate it! Thanks so much, AC.
