GD70 Posted March 18, 2020 Report Share Posted March 18, 2020 Beautiful 3s you have there! Someone did a pretty sloppy job trying to bridge the leads. I'd remove the added wires and replace them with a single strand. You could use copper strands from untwisted speaker wire, pull a couple strands for your repair. Give yourself plenty extra to work with. When you join the copper and aluminum lead, be very careful as the aluminum is very fragile. Carefully make a little hook at the end of the aluminum wire, and a hook with the copper wire that has extra to wrap around the aluminum wire. You can try to solver it together, but definitely wrap with electrical tape. Then solder the other end of the copper wire to the terminal strip. Just heat up the old aluminum solder and remove before resoldering the copper wire with traditional solder. Quote Link to comment Share on other sites More sharing options...
