Electrical security device

Post by **Leyland** » Fri Aug 20, 2004 5:48 pm

Hi again everyone

I am just putting a new wiring loom in a 1962 car. Mindful of additional security, I used to have a hidden toggle swt for the fuel pump.
I have thoughts of a slightly different circuit. I am just about to wire to the ignition swt. What if I take one of the white cables (the one that goes to S3 fuse & supplies the fuel pump and ign coil) and route it via a hidden key swt. I have a 12v 10 amp swt with a detachable key. The idea would be to leave this swt on in normal use, and then isolate and take the key with me when leaving the car vulnerable.
On turning the ignition on, the ign light would come on but there would be no supply to S3 ie: the coil & fuel pump.
What do you think of the idea. Would a 10amp swt be adequate for that particular circuit. As far as I can see it only feeds the pump and ign coil.
and the circuits of S4 (all green wires) Your comments would be appreciated.
Ty

Be careful... I had a switch like that short out, taking half the ignition wiring with it... lots of smoke &c. &c... not nice when you were previously doing 50mph at night. Had to aim the old girl into a field, but thankfully the damage was very limited. You would need to make absolutely certain that 10A was enough - what if there was a short in another part of the circuit??

I'd much prefer the idea of a fuel pump switch - that way, if the toe-rags get hold of the car, they'll be no further than the end of the road before it dies on them, and then stranded in the middle of the road, with a stolen car, they would IMO be more likely to scarper.

LEYLAND, if you have the standard ignition circuit then let me
know and I will advise you of a thief proof system via an e-mail.

Hi Willie
thanks for that info, I have sent you a private message with email details.
cheers

Hello all,
firstly, if someone really wants your car then there is virtually nothing that will deter the determined thief. Having said that, secret isolation switches can easily be bypassed. The real point of this post is that I recall that Volvos of the 60's had the coil terminals completely out of sight. I think, from memory, the top of the coil was inserted into the bulhead and a quick 'hot wire' was impossible without pulling the coil out.

hi willie

why not share your security device with us all, or is it that top secret.

ok now come to think about it unless there are maybe some who may log on who we might not want to let them know.

the best anti theft electrical trick is to remove the rotor button and take it with you, not may crooks carry spares with them

there have already been problem (only 1 that I heard of) from people who have used the site to find locations of stuff to steal. It pays to be careful.

As Ray says it pays to be careful, if someone asks anything of a securtity issue it should always be replied to by a PM and then you have to be careful that they are genuine owners.

That's why I said I would contact LEYLAND via PM. I got
told off once on here for telling an owner how to start his car
when he had lost the key! Not exactly rocket science but someone
took exception.

My insurance company insisted on a cat2 imobiliser and alarm system, so i have a cobra systems professional fitted that imobilises the fuel pump and ignition system.

After the installer had signed the certificate off I started the car xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxx bypassing the imboliser in about 15seconds he was horrified..

I am putting my money on the Cat 3 stop lock pro and soon to be fitted brake stop valve that makes the brakes stick on. As from my own experiance you cannot stop a minor from starting even with switches and imobolisers as it is so simple to hot wire

Well it's nice to have a steering lock on my 55

It won't stop a proper proffesional who steals to order, but it will really surprise the imbecelic idiots who do a lot of the car crime on old cars.

Here's a sideways though. If they cannot get into the bonnet hot wiring becomes increasingly more difficult.

I don't have any cool ideas on locking it.

anyway food for though.

i had though of how to lock the bonnet, but as you can lay on the floor and reach in to the engine bay and unlock it ( after forgetting to fit the split pin to the bonnet leaver

)

Well if any lurking potential thieves didn't know how they certainly do now!

How about telling them how to turn the engine with the starter motor from under the bonnet as well?

Pretty obvious though 57, any lowlife that CAN'T start a Minor in the aforementioned way has no buisiness calling himself/herself a 'car theif' and they probably should not be allowed out without supervision!!

These 'alarm and stereo installers' really do get ideas above their station sometimes (I used to work with a lot - and used to be one for a short time). It does them good to show them how potentially useless their systems are, and it's only because of a bureaucratic need for the paperwork that they are really there at all!

True Cam, hence my use of "potential." The so called installer should have incorporated the l.t. and fuel pump supplies into the system, or maybe it was. My only concern is that a great deal is made of using the PM system when issues of security are concerned and then an open post of how to bypass any security that could be in place.

I would presume that most people could hotwire a minor... an most other pre ecu based cars with little effort

I am strongly of the beleif that a mechanical imboliser is of much more use to us

have removed the hotwire instructions form my post to stop any woodbe minor theives that are brigh enough to surf the web but not hot wire a minor from doing it

Maybe so (excuse my ignorance here) but a Hot Wire sounds a dangerous thing to use to me

it's ok but the aspetos gloves are more dangerous!
