So, engine doesn't start intermittently. After corrosion x in the solenoid, cleaning contacts, problem re-emerges. Can start engine by pushing button but need to fix this. Broke out spares purchased across the years and noticed my spare solenoid is 24 volt (need a 12 volt). I have a Cole Hersee 12 volt solenoid (no button) but am not sure if the wiring relating to the "s" and "I" marked small terminals on the solenoid relative to the red and black wires on the existing valeo solenoid. Any thoughts ? Internet research suggests red to "I" but I'm not confident enough to do it. Of course will order correct solenoid when possible.
