Can't get RC2 to go high with PORTC.2 = 1

Hi, Jellis


I'd appreciate A look to this part of the scheme !

Alain, thanks for the reply. I tested the code again watching closely for the 5 sec pause and notice strangely that it never does pause for 5 secs. This really puzzles me. Any ideas why this would happen?

Am enclosing a partial schematic that shows how RC3 is interfaced to a SPST relay that controls power from the battery to another single stable DPDT relay, which switches the power between two polarity switched outputs, to SOL_RED when RC2 is not energized and to SOL_BLK when RC2 is energized. My problem is that RC2 is never going high by the code so the DPDT relay never energizes into the SOL_BLK output state.
