I had a leak in the low airpressure switch and ordered a new one from gillig. The old switch just had one connection and the new one has 2 connections, labeled 0 and the other labeled NC. Which terminal do I connect the one lead to? And what do I use to seal the threads and how much torque?
I also ordered a new water temp sender and a 225 degree temp switch. What torque and sealant to be used on these two?
Thanks

o = open
nc = normally closed

you would normally connect a low air psi warning device to a nc circuit. once it builds up past 60-75lbs air psi opens up the contacts and the buzzer stops going off. seal with teflon typical 60in lbs - overtightened and it could mess up the readings on the temp sender.

here is a recent tech article that might help
