I am having a weird problem with a CTH build.
The relay keeps tripping on and off and then stays off for extended period of time and then randomly starts switching back and forth again before settling to the Off position..
All voltages except for OL-> SG and OR ->SG check out.
I tried swapping the opamps out on the buffer and the E12 just to rule them out even though i was getting the proper voltage readings on the E12 opamp (Pins 1, 2 and 6 were at 12 volts)
The problem I think could be with a possibly faulty relay or the coil voltage not being right.
Relay pins 1-> SG and 12-> SG read close to 24 volts..this has to be wrong as the coil nominal voltage is supposed ot be 12 volts at least for the relay to be actuated.. Right?
Pins 3,4,9 and 10 all read 12 volts with respect to SG.
Here is the relay part
Appreciate any input.
