Yes, I suppose you have to get it just right, with enough of the wire in
there to stop it backing out. I started doing it with mains plugs (in
the days when you regularly fitted them yourself, and had to
occasionally attend to them), because I often found them with frayed
wire inside. Bending the wires down, and screwing down onto the sheath
was something I always found reliable. Hard to describe exactly, though.
Yes, I'll do that if I can. Not always easy with thin stranded wire,
but it means you have two screws holding the wire, instead of just one,
and maybe don't need to crush so much. I once did an emergency repair
on a car clutch cable with one of these, and it allowed us to finish a
touring holiday. So you might say I have a bit of a soft spot for them :-)
Following up my original post about replacing a failed wiring loom which
prevents the heater fan from operating on a Peugeot 307sw - the new
speed control resistor & loom end arrived today.
RS hadn't delivered the Wago connectors by lunchtime - so I ended up
using some heavy-duty blue crimp-on bullet connectors instead.
If any poor soul is going to attempt this repair, it's made a tiny bit
easier by unclipping the wiring loom that connects to the speed control
switch, and unplugging the two wires that go to the heater fan - but
tape something on to them so you can retrieve them later. Gently easing
the resistor end of the loom down will give you just enough room to get
a crimp tool onto the cut-back ends of the loom. It's then relatively
easy to feed the whole lot back up through the 'recirculation' air vent,
and give it a quarter-twist to lock it into position.
If you don;t have arms like a gibbon and hands the size of a
five-year-old then it's not quite so easy. Grr!
I think my local mechanic must have been getting a bit tired when he
gave up on the job, 'cos after reassembly the fan was spinning but not
blowing a lot. Swapping the polarity on the connections to the fan
resulted in a fan that blows rather than sucks!
Apart from a bit of a 'hot' smell for the first 10 mins while the new
resistor baked itself clean - all now seems good!
Now for the air-con!
I'd use the latter without a second thought in a car:
1) They are suitable for stranded wire;
2) They are resistant to vibration;
3) Well shielded - the sheath goes into the connector some mm, no change
of accidental shorts.
