| Subject: | fusible link construction |
I've been reading the daily digests of the posts for a whole lot of years
but this is my first post.
I've used fusible links following Bob's instructions thru three airplanes.
It has occurred to me that using DB9 pins secured with heat shrink instead
of butt splices makes them more easily replaced. Do any of you have
reason(s) to suggest this is a bad idea?

I can understand the motivation, but my attitude is that as reliable as
subD pins are, it does add more joints to the path. And links are typically
used where there's virtually zero risk of them blowing, unless there's some
sort of catastrophic failure, so the risk of issues from the extra joints
may well be higher than the odds of needing to replace the link.
Just my opinion, though.

Bill,
Lines with fusible links are usually relatively high current. You need to
be sure that the wires going into the pins and the pins themselves can hand
le the current. Otherwise the pin connection might become the fusible link
.

Agree with Charlie. How often do you replace fusible links in your car?
Simpler is better.

There are a few places where relatively low current links are used; the
alternator field circuit comes to mind. You certainly wouldn't want to
try the little pins for really high current.
