    Thanks for your reply Harry. I didn't change anything yet till I find out what I needed to order. This is about week 3 of me doing all this. The tractor had a/c two years ago but developed a very slow leak. I can't locate it and I am not sure if it still exists since it holds pressure now...

    Tn75s air conditioning relay

    Thanks again Lou! I have that chart as well. I read that if looking for a restriction/obstruction you can actually feel the piping of your system and follow the temps and drops in temps for possible blockage. I am yet uncertain if I even have a blockage. I just came in because it was so hot...
