great clip   You see what I mean about  wanting a wider angle lens though?

If you stick one of these on http://www.ebay.co.uk/itm/251313212591 it will work though these http://www.ebay.co.uk/itm/111113168518 look better and thease for extra wide www.ebay.co.uk/itm/290897877782

Gosh! Now I see the hexagon. Thanks.

No that's not what we have been calling a hexagon  .  That is a bolt head as written in the description and is a male fitting.  Requires a  socket (female) to undo. A hex fitting is a female fitting i.e. with the hex inside and undone by a male hex (allen) key. Apparently there are three fittings, bolt head as shown, hex like I have and torx which I have never seen, presumably a female torx requiring a male torx to undo.

You might try a Bosch PMF 190E http://www.tooled-up.com/review/bosch-pmf-190e-set-all-rounder-3-in-1-multi-tool-cuts-saws-sands-190w-240v/198475/

Well done .  Welding is great fun to learn, try to start on gas, move to arc and then MIG which is most difficult to easiest.  MIG then appears as a joy to use, just like a giant glue gun. My first MIG welding project was a custom set of car ramps wide and low enough to get my first omega up on without scraping the bodywork. Always trusted them, still use them.

Plasma cutting is quite rewarding too, better than gas cutting.

These new bluetooth OBD2 readers look remarkably cheap  www.ebay.co.uk/itm/221249319122.  I'm sure they are a total waste of £4.15 but I'd be pleased to hear why.

Alternatively at twice the price www.ebay.co.uk/itm/350800985035

Omega General Help / Re: sun screen

« on: 17 August 2013, 00:16:29 »

Solved this today thanks to Tescos selling off half decent sun screens for 38p each.  Bought two, they are too small on their own but I custom cut one and stuck it to the other with spray adhesive.  Now I have an exact fitting sunscreen for the windshield sunshield for the windscreen.   So now the summer is officially over.

« on: 16 August 2013, 02:36:44 »

Buy a cheap hotel type safe for about £25 and once or twice a year top it up with cash.  Or even one of those 'safes' that looks like a tin of beans or a book.  You'll lose 0.5% interest on the cash mind

Omega General Help / OhMG

« on: 16 August 2013, 00:37:18 »

I now have a battery minder installed.  On test it cuts the battery off when the voltage under load drops to 10.9V for a period of time.  That is Ok, believe it or not it easily leaves the battery with enough power to start the car (returning to 12.3V if left to rest).  I wouldn't mind if the cut off was higher but my main aim is to reduce the draw of the device which is 17ma.  Not a lot but seems to defeat the purpose if the device itself is draining the battery. The device is potted so I can't get at it but I assume the 17ma standby draw is a small solenoid. Obviously I can't get the draw to zero but a bit lower would be good. 

So what I'm planning to do is put a small resistor inline between the device (which is bolted onto the 12V+) and its wire to the negative terminal to reduce the draw and probably up the cut out voltage.  I'll just play around with a few different resistors but can anyone suggest a starting Ohm figure? I assume 1/4W rated resistor will be OK but may use two 1/4Ws in parallel.

Can't wait to see a pic of this please put one up when you're done. It seems the guide may need updating, all very mysterious.  Looking at mine (2.6 V6) the hex female is immediately at the top of the bolt, although the bolt is hollow there is no need to insert the 12mm hex key more than 10mm into it, in fact I don't think you can. 

I can see why the female hex socket might look like a torx if you can't see it clearly, the hex corners are depressed a little for some reason so its not a pure hex but not nearly as much as a torx.

General Car Chat / Re: Automotive electrics - crank sensor testing EXAMPLE

« on: 15 August 2013, 12:51:30 »

And to confirm a car has a ground but not an earth:

A ground is considered to be a 0V reference (e.g. ground plains etc).

An earth is a reference which is at the same (or very close to) the earths surface potential.

Important to remember as the ground on a car could be many thousands of volts above the potential of the earth, this will become more obvious as electric vehicles are used becuase under a fault condition the vehicles chassis ground could beocme live at mains volts.

Are you sure?  I would expect the car to only ever to become live with respect to the battery negative, never the earth (planet), even in fault conditions.  For example if you connect a multimeter to any battery positive and the other lead to the earth you stand on, there would be no reading (or next to no reading).  Unless somone has bolted the battery negative lead to the earth (planet)!

I suppose its possible for the negative lead to become detached from the battery and touch the ground (planet) while at the same time the positive lead becomes disconnected and touches the car body, or more likely just the positive lead to become detached and touch the earth (planet).  Then the car body might become live with respect to the planet .

I read that a TSB was issued in 2001 about 'voltage spikes from the alternator damaging the camshaft sensor. This is prevented by unpicking the wiring loom and re-routing the cam and crankshaft sensor cables together around the front of the airbox, keeping them away from the alternator. ' I wonder if the same spike damages the crank sensor. Or was the crank sensor already routed away from the alternator (I didn't think it was close anyway)?

No thanks mate I have done the same as you and put spin on filter on. 

Right I'm going to bin my spare paper holding cartridge.  It seems they are not as popular as I was led to believe   Anyone who replaces a stuck cartridge with the same must be a masochist.  Spin on is the way to go!
