Hi,
I'm trying to solve a problem with a spark coil, but maybe the solution could also benefit coilers in some way.
I've exposed a small section of the outer layer of the high voltage secondary winding. The wire is very small, I can barely see the individual strands. Here's the problem: 3 or 4 of the strands are broken and I'd like to repair them. I'm not trying to reconnect individual broken pairs, I think it would be good enough to just "short" all the broken ends together. I don't think I can use a blob of hot solder because I don't think I can adequately prepare the ends to bond to the solder, and I don't want to risk heat damage to the surrounding area. Also, access to the wires is limited, kind of like in a hole. I don't think I want to use a conductive paint or glue, because if it doesn't work then I may have made things worse by adding something which would be hard or impossible to remove. Here's my idea: use finely powdered silver or copper to try to fill the area around the breaks, maybe using a little liquid carrier which would evaporate cleanly. My thought is that enough powder would allow electrical contact among all the broken ends. If that works, then I would probably seal the repaired area in some way.
So, do you think the powder would work? Do you have a better idea?
Thanks in advance for your comments!
Tedd
