Given that money is tight at the moment ( the radiator went) if you had to
choose from steering lock, imobilizer or wheel clamp would you pick and
why???

It seems that each one has merits and shortcomings ( as usual). I'm leaning
towards a good steering lock. He says he prefers the immobilizer, the
problem being hes fitted several to petrol engines and is not sure of the
wiring for diesel ( assuming its different ??). I think the wheel clamp
might be beyond my capabilities with my back bending is not a strong point.

TIA

Wheelclamps unless they are the very expensice tailor made ones for your
particular wheel size, are very easy to get off, a long bar can usually bend
them open, and the fact that they have to be adjustable for a wide range of
tyre widths and heights, not to mention have thin bars that hook round the
back of the wheel to clear the many obsticals on different vehicles makes
them weak, anyone who's had a caravan stolen will be able to tell you all
they have left is the bent wheelclamp,

There are companies that make wheel clamps up to fit a particular vehicle,
but even then any commercial vehicle has a range of different wheel and tyre
sizes, but they are better than the universal clamps,
obviousely for a few hundered quid you can have one made up that fits only
your van, and wil be almost impossible to get off with out the keys as it
will fit like a glove, and have the arms in just the right places to be
strong yet clear the brake calipers, drive shafts etc.

A steering lock can be got off easy too, apparantly it takes about 10 to 20
seconds to remove them with out dammaging the wheel, if someone wants your
vehicle for a joy ride (ok, unlikely for a motohome but you never know) then
they can just cut the steering wheel it's self and slip the lock off, seen
that done many times on cars when i used to recover them after being stolen
and dumped.
But a steering lock is a highly visable deterrent for the casual theif, and
can slow them down, and that's all you can do for a determined one, as if
they want it, they'll get it, the scrote off the street who thinks it'd be
kewl to nick a van will hopefully be put off,

The imobilizer can be a good option, but cheap ones can be got around,
they're wired in similarly to one on a petrol engine, where on a petrol
engine you cut the low tension wire to the coil and insert one of the
imobilizers cirsuits, you cut the power feed to the fuel pump stop solenoid
as this does the same things as the low tension wire on a petrol engine..
stops it running,
you can also cut the starter solenoid trigger wire, that's the same as on a
petrol vehicle,
if there are enough circuits, and probably using an external relay you could
cut the supply to the glow plugs (if your van needs them to start, most
direct injection diesels only need a glow plug in the extreme cold, on my
van the glow starter devise only works when it's below 2 degrees C, at all
other times the engine fires up the second the starter touches the ring
gear, indirect injection diesels need the glow plugs all the time when cold)

But assuming you have an indirect injection engine, then you could have the
imobilizer interupt the power to the plugs, i'd personaly interupt the power
signal to the glow plug relay rather than the actual power to the plugs,

a little inginuity and you could interups power to items needed to drive
with out attracting the attention of the police, indicators or brake lights,
maybe even the headlights if you have a fail safe imobilizer.. i.e. one that
can never come on while your driving, yet if a thief nicks your vehicle,
which is most likely to be at night, he can bypass the starter and fuel stop
solenoid and maybe even the glow plugs to start the engine, but he'll
attract the attention of everyone by driving with no headlights,
these are all things you have to wire in your self, and can be done if you
have a basic understanding of a vehicles electrics,

At the end of the day what you have to do is make your vehicle look like a
worse target than the one your parked next to that has no security, the
thief will often go for the easiest route, and if your next door neigbour
has a van with no security at all, and yours has, you can guess which one
he'll nick,
sounds horrible put that way, but if the person you are next to on a
site/car park has security, then the thief will go on to the next vehicle
and so on, you just have to make yours look unatractive to a thief.

There are simple things you can add to, a battery disconect switch hidden
somewhere out of sight if possible, and an auto re-setting 10 amp circuit
breaker accross it, when the key is removed it'll keep the radio and clock
memory alive, but attermpting to start the engine will trip the breaker,
making it look like the vehicle has a fault with the electrics or a flat
battery, (mine will allow the starter to clik, just like a flat battery, but
holding it on for a few seconds kills all power to the van, which returns
about 20 seconds later, and you can repeat the process, hopefully that'd
confuse someone long enough for them to worry about being caught and make
them go away.

add a hidden switch that connects the horn to the brake lights, when the
thief wants to slow down the horn sounds, or maybe even better a police
siren sounds, if it dosent scare him off it'll certianly attract attention
of others

We have an immobilisor which works off a little plastic fob gizmo which goes
into a slot on the dash. You pull it out and take it with you when you
leave the van. 20 seconds later, the starter won't work.

Neat little thing, but I accidentally sucked it up the hoover nozzle at the
weekend and had to feel around inside the dust bag to retrieve it........

When you was there, you did not find by chance the back off one of my
girlfriends Earing's?

steering lock


The Halfords steering wheel lock/cover is cheaper than its big name
competitor (which we did not try), but there was a detail review of
these in a Mag

I copy (with identity removed) from elsewhere a posting summarising
an article seen in Practical MotorHome - Oct/Nov 2002 - a fairly
comprehensive review

================================================== ==========
The Magazine report on steering wheel locks selects the
'Halfords Wheel Shield' at 59.99 as the best buy.

It claims that their 'Naughty Lad' took 5 minutes and still could not
remove it although its main criticism is that it is fiddly to fit.
Apparently the
'Autolok 2000' is identical to the Halfords but 10 more expensive.
The
'Diskloc' is as good as the others but heavier. The cheaper models all
failed to satisfy the reviewer for various reasons the most common one
was that the 'Naughty Lad' could remove them all fairly quickly - the
'Carpoint Elephant Lock' , for example, at 10 was removed in only 6
seconds!!
================================================== ==========

I use the Halfords thing. It is large etc, and true, *is* fiddly to fit.
Compare ease of use with the more expensive version too, may be similar.
Also have a manufacturer fitted immobiliser, and a Yale extra lock on
the living door.....
