I have a 93 chevy k2500 with a manual shift transfer case. Bought a new actuator and position sensor on the top of the transfer case. But as soon as I plug everything in and start the truck in 2wd front actuator engages. No matter how much I roll back and forth it doesn' come out. If I disconnct the actuator and battery, then reconnect the battery but not actuator or position sensor it is fine in 2wd but no 4wd lock up on the front end. Then plug everything back in then everything locks up even though transfer is never shifted out of 2wd. Could an open ground cause this? Or another sensor some where?
