1990 K1500 4x4 Issue

[jackyl9999]

I just purchased a 1990 K1500 350/5 speed. I found out today the 4wd is not working. So I did some research, I bought a new actuator, and installed it this afternoon. I can place the transfer case in 4hi or 4 lo, but the front axle will not engage. I have waited and gave the actuator time to work (it is a cold day here) and it will not work.

I unhooked the actuator and put a voltage tester on it and am getting 13volts to it when the transfer case lever is moved to 4hi/lo.


What else could the issue be?
