it shouldnt.
But I do know that on those machines, if 1 of the 2 red wires loses voltage, it can fry the SWIM, I have witnessed it first hand.
what it does it cause the 5.2V to lose regulation, and will show AC adapter voltage at 7.5 to 7.8VDC, and the SWIM gets hit first.
And to be honest, after following a couple threads, the wiring harnesses are starting to become problematic, Whether its the microswitch or whatnot.
The microswitch if I recall is double-throw. Meaning there are 3 wires that go to it.
If the microswitch gets bad to the point to where the normally closed position is open as well as normally open, it CAN cause the 1-wire only voltage situation which frys the SWIM and causes a shitload of other regulation problems.
