Reply To: QD15 coil – can I use this one?

I’ve repaired at least a dozen coils with the same common condition using heat shrink tube. However, none of the repairs had quite as much damage as the one pictured.

The repairs all worked as long as the smallest diameter shrink tube is used, and care is taken to ensure that the wire is tight to the “back” of the coil.

I would definitely make every effort to save this OMC coil. After the repair, how about testing it with an ohmmeter. It doesn’t seem as though that tiny wire carries a lot of current, and it may work fine.

I like the marine heat shrink tube that has heat activated adhesive on the inside of the tubing. It seals up well.

Just one more opinion to consider.

Stick around long enough and you will always learn something…

I didn’t realize they made a marine grade heat shrink tubing.

I’m going to search up some of that and give it (along with a very careful solder) a try. I have a donor (toast/dead) coil that I got off of my Sea King. The plan at this point (depending on what I find when I take a magnifying glass to the wire damage) is to cut the wire and solder on a new lead the same length with the shrink tubing installed upstream from the damage. Once the damage is repaired, I can move the tubing down and shrink it up. I also might use some liquid tape prior to the shrink tube.

Thanks all!

Back to work…
