Update! After testing, I discovered I had the 12v at the solenoid but not the ground. I placed a temp ground from the frame to the solenoid and Presto! 4wd back in action! Due to the weather, I will troubleshoot the open in the ground when it gets a little warmer, but for now, I will be able to plow the driveway without issues. Thank you James and jabelding for your help on this! Also, a big thank you to Concord tractor in Chichester, the owner called me right before I started working on the problem today with more advice on trouble shooting. They are a class act, and have my business from now on.
