Reply To: Electrical riddle no.7 – Over size diode problem

    Quote: “I’d say you’ve welded the dry contacts in relay #1 by some means every once in a while. (possibly the same over-current situation that is taking out the diode). Have you checked the current draw on a recording basis, and compared it with the rating of the relay? ” You mean dry-contact by Dry-switch operated by its own coil & not the contact of R2? I took it as the NO contact of R@. Regards
