I was told that is was possible my LM pins 2 and 3 may have been reversed. I switched the LM pins. Basically it is still the same scenerio. Only difference now is the relay "chatters" (ocsilates) at the V transition. Still cannot adjust past 3.95V, I will explain my readings. I am using a 12V light as my indicator for now.
Vset 3.60....Source V 3.64 Light on
Vset 3.65....Source V 3/69 Light on
Vset 3.70....Source V 3.75 Light on..etc
Vset 3.60....Source V 3.55 Light off
Vset 3.65....Source V 3.60 Light off
Vset 3.70....Source V 3.65 Light off..etc
So above, the circuit works as designed (as it did with the LM pins as before)
Keep in mind that it is reversed when I switch to the other "pole" of the relay, in other words, Lower VSet Light Off, Higher Vset Light on. But this is how I want it operate.
Vset 3.95 to 5.0v...Source 4.0 or higher Light off, never turns on. Even if I swing either voltage up or down. Likeit ceases to operate.
In other words, once my source gets to 4.0v or higher, I can no longer adjust the V set to turn it on or off. Whether the Vset is below, or above the reference of 4.0 or greater, the circuit just doesnt operate. I can have the Vset at 4.9v and the Source at 4.0v and it will not turn off.
Any Ideas?
