Put the unit back together and test. Light bulb connected across the monovalve is lighting up so it is getting a ground again. By turning the temp control dial to coldest detent click, monovalve is on constant (light on= no heat). Temp dial on hottest detent click monovalve is off (light off = full heat).

Still need to road test with AC on to make sure it works.
