then i tested the blue/yellow wire going into the diode and also got a 1 reading. i deff got a zero yesterday. -pic 1 and2

finally i tested both of the red wires coming out of the diode and i got a 2 reading. - pic 4

the last pic reading a zero is just to make sure i have this thing on the correct setting lol. -pic 5

Was that with engine off or rotating?
What about the other tests?

1) Ground the negative leg of your voltmeter.

2) Turn the ignition key to the on position, but don't start the engine.

3) With the positive leg of the voltmeter, touch the naked metal dots on the top of the fuse #5 (headlight / 10 A / gray wire)

4) If volts' reading there (value does not matter), follow that grey wire up to the headlight relay. That relay has our gray wire, one blue/yellow, one yellow/red and one red. We will need to measure the voltage at the yellow/red and at the blue/yellow.

5) Start the engine.

6) The yellow/red and the gray wires should have measurable voltage with the engine rotating.
