Default Could This Be The Cause Of My PCM's Going Bad

I was testing some of the wires on my Chrysler Cirrus and i found something weird and i don't know if it should be like that. but when i tested my ground wire blue and black. i got a positive and a negative reading on the same wire.
I also tested this with test light.
I'm just wondering if it should be like this or not

Its an 1996 Chrysler Cirrus LX 2.5L V6. The car will not start and the PCM is the problem this the second PCM put into the car.
was testing Sensor Ground K4 Black/Light blue. I test this for ground and positive at different times.
