On Wednesday I started removing the level sensor on our Discovery. Engine off, wheels chocked. Before trudging off to the shed to get the axle stands, etc., I gave the sensor connector a quick prod with a screwdriver (so see how much mud and muck there was round it) and it came apart. With a loud hiss the suspension went into an emergency mode and trapped my arm between the wheelarch and the tyre - it was now the only thing taking the weight of that corner of the car and it wasn't going to shift.

Now, I knew that would happen when I removed the connector and I had planned when it would happen; the plan included a couple of sleepers and the axle stands being in place beforehand. It didn't include a 'premature disconnection'.

If anyone else had done anything like that I would have them hung, drawn and quartered, put their carcass in a gibbet with a large 'pratt' sign above it and then shout sarcastic remarks at the rotting remains (whilst sending crows to peck out the eyes).

The result was:
  • Two fire engines...
  • One Paramedic ambulance...
  • Fire chief's response car...
  • One neighbour with a slipped disc...
  • One neighbour with a suspected hernia...
  • An offer of an air ambulance trip...

Forty-eight hours later and there is not a mark on me - I am so skinny and muscle-free that there was no flesh to crush - my bone took it all. I don't like to think what might have happened if I my head had been in that gap.

They were all very nice and they commented on the fact that a) I wasn't swearing (much) and b) I apologised for not getting up or shaking their hands.

Only once did I shout "Mr Grimsdale!" when "Help!" didn't seem to be cutting the mustard.

Moral of the tale?

1) Never think it won't happen - assume it will. You'll be wrong 99% of the time but that 1% will make it worth it

2) P*ss-taking from colleagues and friends is a very strong deterrent against anything similar.

The epilogue to this tale is that yesterday I snuck out of the house whilst my wife was busy and installed the new sensor. Startled to hear the front door open (I knew I must have been rumbled) I sat up with a start and hit my head on the open rear door.

Its off to be calibrated this morning.
 
that's why the RULE is to disconnect the battery before you work with height sensors... it's stated in all the "how to"-s ...simple as that... then no recalibration is needed aswell
 
There but for the Grace of God go many of us, not just with cars either.

I had an apprentice take a ride across the main road by Reigate station on a trolley jack after he jacked a TK Bedford up at the back axle. Handbrake is the same as a Discovery, so as soon as the wheels left the ground the truck just ran off the workshop slope and across the road with him hanging on for dear life.

That was at E J Baker, Bedford dealers.

Had a few others over the years, one in Libya involving a generator on a film, another in India, ditto.

Survived most of them :)

Heheheh, we've all. 'specially me, done daft stuff, thankfully getting away with it, but hopefully also learning much from it.

I have, I now don't go first through rivers and fords ..

Well, I will actually, but YKWIM .. :)
 
I'd really want to be your neighbour - NOT !!!


Although watching from a safe distance, it must have been funny - not for you of course :flame::D:D

The prod was part of an initial "reconnoitre". I also had a railway sleeper to bung under the tow-bar as a backup stop. Never, in the field of automotive tinkering, has a connector come undone with so little force. The new one snapped back in nicely.

Still, I had to get behind the radio this morning and my arm fitted the hole in the dashboard perfectly.
 
I probably would of crapped myself if that had happened to me! Glad you're unharmed! Lesson learnt the hard way I guess ha ha.
 
Fair play to owning up and posting the safety warning! :cool:

My D2 has had the coil conversion but the height sensors are still there. I've been told by fellow LZers to leave alone - I don't know if the electrickery is still talking to those sensors despite no airbags. If the D2's brain IS still communicating with them, then I'd need to go through a re-cal or whatever needs doing = buggered Landy for a little while :(
