Buccaneer,
I have repaired coils (with success thus far)that have had the tabs broken off. I’ll try to attach some pictures of the process.
First I cleaned it all up and found the hole in the hard covering. Then, very carefully cut around that hole to find which direction the wire that came out of it ran under the hard covering.
Then expanded the hole in that direction to get more wire, enough to be comfortable working with and gently (!) lifted that wire out. I then soldered an extension onto it, tucked it gently back down so only the new wire was exposed after refilling the hole with epoxy.
I took all the advice about being gentle and real conservative with heat.
I used to have a putty clay like stuff that I’d put around an area to be welded to dissipate heat, but I just used a wet shop towel this time. And gentle air blasts.
Geer
