Please indicate if all parts are installed, and if not, which ones are or are not installed (may as well confirm values while you are at it). | |

Insufficient margin for aging may cause it to work okay today but fail later. Relay not pulling in smartly may cause premature contact failure. These things are not necessarily mutually exclusive. | |
