Sensors are on their own loom, might be worth double checking the plug just before the loom exits the boot to behind the bumper

That said if the box can't 'see' that the car is in reverse, then the sensors won't be activated

Will do. It will now have to wait until tomoz. Fortunately the TD is my daily, and the 3.2 is on stands having had all the AC system dealt with, so I thought I'd deal with the PP while its off road.

Thanks again Al, I appreciate all your help.

[Shackeng]

However all this is odd in that the speaker is also dumb.

[Entwood]

Once its back driveable, if you want to pop round with it we can use some long wire and jump speakers/systems one to another and see what is working or not ?? But we go away a week tomorrow for a couple of weeks (France)...

Thanks a lot Nige, I will probably take up your kind offer.

Cheers:y

A fault with the sensors will send a series of beeps.

Not sure of the buzzer you are using..... I tried a front door speak from a Bose car and got nothing (it had resistors and stuff).... a simple PC speaker gave me instant results.

This is just a 12v buzzer, works OK off a 12v battery, and I assume the signal to the PP speaker is 12v. I get no beeps or any noises at all at the moment.

No current from the PP control module when the car in reverse?

Do the sensors tick, if touched lightly with pp engaged ? (Engine off helps as said)

The pressure applied to the centre of the sensor needs to be very light or the ticking will be smothered. Its quite subtle.

The speaker is a speaker, not a buzzer, isn't it?

Thus 12v across speaker would only give, at most, a quiet, single tick.

.. followed by a little whisp of smoke, yes. 

Easy to replace with a speaker from an old radio, etc. IIRC we did this on one of Chrisgixer's cars due to a failed speaker.

Fairly sure RobG has used a Mig Tweeter in one of them, need to bypass the Cap and Coil (Crossover) on it though.

As many of you will know, such language is foreign to me.

So if the speaker was OK I've now blown it up?

On the plus side, you don't know that it was actually working beforehand

Roughly translates to... use one of the small speakers in the front door by the handle, remembering to remove the little electrical component from between the terminals

I think...
