Ok so I lost 4 high the other day so I replaced the actuator switch. I have 4 high again but still no 4 low. Now I have never had 4 low since I bought the pickup. I was checking voltage at the dash switch and at the actuator. In 2 high I have 4.45 V, 4 high I have 2.3 V, in 4 low I have 1.5 V. On the 2 pin plug on the actuator, there is no voltage in any switch position. On the 6 pin plug on the actuator, there is 11.35 V in any switch position. the t case will engage in to 2 high, 4 high, and 4 low manually but the actuator will only go into 4 high. I'm leaning towards a bad dash switch but I don't know what the correct voltage should be. Thanks in advance.
