Was about to ask if the intertia trip operated when you unleashed big bertha on it.. but that cuts the fuel pump IIRC.  :-/

Did you say it's got a spark?

Fuel pressure in the rail.. OK, but is there drive to the injectors when cranking?

Immobiliser issue?

It does then start to come down to crank sensor...

Well, that's the no-claims protection on your post count topped up!

On a serious note, it's true. A great bunch. Long live OOF!

I still don't have new cambelt on and the VX instructions seem trial and error (and what an error if you get it wrong!).

At the end of the day, as long as you turn the crank through 2 turns and check the alignment of the cams afterwards, and repeat if there's any doubt there shouldn't be any catastrophes. Would be a hell of a lot easier with markings on the belt though

The cam belt procedure for Y26 and Y32 engines states that this pulley is fixed so I'm guessing it was a change on these engines.

Procedure is to line up crank to 10 degrees before TDC, install belt and tensioner then advance crank to TDC and tension belt. I guess the extra 10 degrees is a guess at what it'll take to tension the first run of the belt. Trial and error, though, especially with no markings on the belt

Welcome home. Hope you had a great time. You missed some really shocking weather while you were away so definately a well timed break!

More and more down here have got all the parts on the shelf, they will not allow you to rummage anymore.

Same here. It's the little parts that you have to rummage for that make them so valuable though. Not valuable enough for a scrappie to keep on the shelves but unobtainable (or stupid prices) new.

A tragedy indeed. Poor chap.

I wonder how much longer there'll be scrappies where you can rummage?  :-/

I get a code 32 from my climate with a cheapo tech 2. Maybe it's a quirk of the cheapo Tech 2? Or maybe there's a procedure to be followed - i.e. test it in the dark or something?

I like the sound of the upgrade though. I am constantly turning the fan speed down on mine. It seems to go to full fan speed any time there's a 1 degree difference between actual and set temperature

I have a friend's 2235 with a  power fault

Mine failed with a power supply problem. I suspect the cooling fan packed up, closely followed by the MOSFET in (I think) the first stage switching regulator that takes mains down to about 50 volts DC IIRC. MOSFET is mounted to a heat sink just in front of the cooling fan IIRC. Mounting arrangement looked a bit marginal too so I replaced it using a proper mounting kit. That part runs hotter than I would like but has been reliable since.

..really must get something a bit more up to date (and faster!)

Always lots of nice Tek ones always going on ebay for very little cash. Bit of switch cleaner and change the dried up caps and they're fine.

Its the introduction of bloody windows on scopes thats the worst bit.......its like an anxiety detector, it crashes or goes into screen saver mode just when you need all your hands to hold probes and trigger events....

Yes, it's happening to our instruments too. Customer wants to put his spectrum analyser on a network and he also wants to print the screen output. Rather than adding a printer driver and a network stack to the nice, fast purpose built GUI and RTOS the machine has, we port the whole lot to Windows. Now it needs a hard disk to hold all the bloatware that isn't required for a spectrum analyser, it needs virus checking, a much more powerful CPU and customers keep sending them back cos they fall over when they try to install MS Office on them

I think the 465 was probably about the best scope they made. I have a 2236 which works nicely but a sod to work on and clearly built to a price, which none of the earlier 'scopes seemed to. People say good things about the 2465 but I haven't played with one recently.

I have 3 7000 series at the moment. a 7904, 7603 and 7623. Would love to come across a spec ana plugin but they seem quite rare.

I agree that digital 'scopes don't "feel right" in comparison to analogue scopes. The slightest flicker of an analogue 'scope tells you something, which you'll probably miss with a digital scope. However, it's mainly down to user interface and a slightly different approach being required to use them, IMHO. A load of menus to wade through doesn't seem to be a match for a couple of switches on the front panel.

The better digital scopes do work very nicely and don't mislead because they use plenty fast sample rates, but if you're not working on stuff that needs to be ruthlessly fast and you don't need storage, you're still better off with an analogue scope IMHO. I think the mistake Tek made was dropping the analogue scopes from the bottom end of the range because their low end digital scopes are nasty.

I have a rather nice Techtronix 564 oscilloscope....its got valves the lot in it!

My first Tek scope was a 546. Still got it. It got donated to my school by Marconi and the head of science couldn't work it so I talked him into selling it to me, nicked my mum's wheelbarrow to bring it home and promptly got a bo77ocking for bringing "more junk" into the house.

Junk it wasn't, however. It's still absolutely flat to 50MHz+, triggers up to 150MHz no problem and, at 500 watts power consumption, it keeps my attic room warm in winter! It's a hybrid of valves (dozens of them) in the timebase and power supply and transistors in the vertical amps.
