Rally dash oil pressure gauge issue.

This iswhere I am at. I did hook up a 10 ohm resistor, and the guage read somewhere near 1/4 tank or a little below half. I started the car with a digital ohmmeter and it read 10 ohms running. the guage stii didnt move. I am thinking possible dash printed circuit board. I had to solder pins on it when I had it apart, maybe not a good connection. Thinking I should pick up new ones if i pull the cluster may as well put in new boards. Worth a try as far as i can tell my guage should read a little below half and its not . I am thinking it should at least move...:)
