I have a couple of questions. First what is the function of the spring brake override valve in the cab and , when should it be used ? The other question I have is when my truck is running and the air tanks are completely charged you can't shift the transfer case into low range even if you hold the button on the shifter down. If you bleed you main air res down to around 50 psi. it shifts great. Why is this ?

Thanks. That is exactly what I needed to know about the t-case. Anyone know how to test the interlock solenoid or where to buy one ? Do these trucks have any fuses? If so where are they ?
