Re: Rewire Ford Focus


It's a reoccuring problem that I have to track down on some bikes I
own/owned (the vibration on bikes is usually worse than on cars but the
same thing applies to cars) - some alarm fitter solders a connection,
covers it in heatshrink.

Five years down the line, you've got an intermittent fault that you
finally track down to the broken connection inside the heatshrink tube,
because the stiff connection has broken. If you solder it properly it's
less prone to breakage but overall the issue is that you've got
something flexible (two cables) joined together by something inflexible
(the soldered joint) without any other form of mechanical protection.

That's a reasonable point. Hovever, if you use adhesive heatshrink, and ties up the cables afterwards, you can avoid the problem. The fact is that if you use the solder as the electrical connection, then take care of the mechanical issue, you won't have a problem. As you say, the problem is the soldered area isnstiff, and the cable isn't. However, crimp connectors are stiff too, and solder takes up less space and is easier to strap up properly afterwards.

Mind you, my favourites are those people who tin the end of a cable and
then crimp on a connector...


Thereby making sure the crimp doesn't work.....
