I just switched the crank signal and ground back to how I had them which I beleive to be correct. I removed the pin for crank signal at the connector and put in a new pin with a small lead comming off. I hooked that wire to a multimeter and the ground or common wire on the multimeter to the battery negative. It was showing ~2.5v it stayed at 2.5-2.45 while cranking and when I stopped cranking it went to 2.7v I thought output should be 5v? What could cause this?
I also tested the cam signal just to see and it also had 2.7x volts as the signal output. Cranked it over slowly by hand and it never changed a significant amount, less than .1 volt.

I have it wired as the haynes book states.
Pin 1- signal
Pin 2- Power
Pin 3- Ground

I read on here people have theirs
Pin 1- Power
Pin 2- Ground
Pin 3- signal
When i wire it this was I get no signal at all. Zero voltage.
