Hi chaps. I'm looking like a regular cheapskate today, but lots of things need attention at the mo and I don't feel like shelling out fior all of them.

Anyway, one of my door solenoids has fried (big time!) and I tried to fix it but it's waaay past that. Then I went looking for a cheap supplier of these things, and found that Maplins do one for £7.99! Both 2 and 5 wire versions, so they're obviously standard parts.

Try www.maplin.co.uk product code is YD79

Just make sure that they are the same. Nothing like putting the wrong inductive load onto the circuit and frying the alarm to go with the solenoid!

Surely though the door opening solenoid isn't connected to the alarm at all? The locking is done by a second solenoid that disengages the mechanics, rather than an electrical interlock.

Plus, it's operated by a relay which isolates it from everything else. I'm not sure that you need to worry about inductive load on this sort of thing... it's not a tuned circuit :-)

Depends on the system and the car, when it was built and so on. Probably a bit of a simplification on my part and spending too much time with broken Meta systems corrupting my brain...

What's the price from TVR ? I've always found them very reasonable ?

I'll give them a ring, but on previous posts I found a price of £30+ being mentioned... And that was apparently cheaper than the donor car's parts service (Vauxhall I think)

I think the only slight problem will be working out the colour codes and the connecting plug type. On my Griff 99 its a land rover connector. TVR do not use the "door lock open" side of the internal switch its something i wanted to use for a boot opening system.So its only four wires,so the worst case would be the door locking when it should be unlocking, reverse polarity and away you go. However if there is only a couple of quid in it, maybe a TVR plugged one would be easier.
Edit to say the 5 wire is £9.99 i think, not a bad price though.

I managed to short my solenoid a while back - own fault .....

I was told the part was from the tail gate of a ford fiesta, but TVR price was cheaper (~£45 I think). It didn't come with the right plugs or anything, so you have to cut the wires + solder to the right existing ones. Worth twisting them together first to test.
Also you need to remove the spring from the plunger.

Not that complex a job really, just a bugger when it was self inflicted !

Under £10 sounds good, IF it is the same part.

Two wire slaves are all interchangeable as long as they will physically fit in the same space. Nearly all of them have the same spacing on the two screw holes. They can be wired any way and then reversed if working the wrong way, no harm done. The five wire masters are the same thing incorporating a changeover switch which uses the extra three wires. The four wire masters are the same as the five wire but the fifth wire is the earth for negative pulse central locking.

The TVR ones are five wires, just four are used!

Actually they obviously vary because mine was a 2 wire job.

UPDATE:
The Maplin part is a perfect slot in replacement for the TVR one, and works a dream. The only thing you need to do is replace the connector (which someone said you have to do on the TVR ones too)

Result!

So they are using the motor side with two wires and using the changeover swith as an on/off switch - nice move TVR!
