Supco T1113 lugs on amazon for 14-16 gauge wire with barrels that won't crimp so solder. Difficult to slide on the element spaded because it's high heat nickle plated steel vs aluminum. Some solder directly to the element spades because they don't get hot enough to melt the solder.Did you end up replacing the disconnects? I'm having the exact same issue. I'd like to know what you used to fix your issue.
