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?

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.

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 ..

How often do you replace fusible links in your car? Simpler is better. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=510070#510070 ________________________________ Message 5 _____________________________________ Time: 01:31:48 PM PST US Subject: Re: AeroElectric-List: fusible link construction From: Charlie England 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.
