OK , It's backwards in my head..... (K) attracts POS? right? Everything is done but the hook up to the TL431A. I will make the correct connections tomorrow morning and test the circuit. REALLY appreciate your input. Where did you find the data sheet? I LOOKED ALL OVER, and couldn't find one with the explanation of the contact points. Just the symbol. I'd like to bookmark the page. I will let you know tomorrow how it works. And you were correct , in that is was a very affordable way to do it. Like 7.00 for all the parts. Awesome, I thought it would be much more. Thanks again, keep your fingers crossed....... I've burn up a lot of sh...stuff. But I was very careful this time, worked slow and measured all the components. I think it's going to work as needed. Let you know tomorrow.
