after looking over the up grade cable the only thing i used was the wire.
the whole idea of the upgrade cable is to reduce voltage drop so why do they use a longer cable and use the same type of connector as the so called faulty original?
The resistance of the single factory cable is 0.1 ohm,
The resistance of the "upgrade cable" is 0.1 ohm.
the problem is the connection between the header pin and the pin in the housing so you can run a 10mm square cable between these points and it still wont fix the problem.
my solution is:
1: Replace (or clean) the Header pins at CN5
2: Cut the black and red wires and use the trufcon crimp pins at each end. 4 at the power supply end and 2 at the display driver board end
3: fit 2 trufcon crimp pins at the power supply end for the display ( most displays used on this machine only use the +12V from the dedicated bridge but do this any way in case you have a display that needs the +5V
4: fit the keys into the housings
5:shave all the hair off the hairy Knuckles shown in the pictures
