I think those ones are usually filament?

If you mean the VWP sticker sheet, they are a sensible size to stick onto SE5a rocker switches

It's this transparent sheet of symbols etc (in white or black): https://www.vehiclewiringproducts.co.uk ... mbol-sheet

Yes, exactly the same as I used on the rocker switches about 9 years ago!

Cat amongst the pigeons - when I returned home last night, both the 'lost for ten weeks' Chinese lights AND the replacements from vehiclewiringproducts were in the parcel box :shock: I do like the originally-chosen Chinese ones (posted from Singapore), so I shall try those I think! They are smaller (fit the holes I have drilled) and have the built-in warning symbols. New speedo seal from QRG is also here, so a busy time ahead :D

Oh, and I have ordered a cheap air-to-fuel-ratio meter/sensor plus weld-on boss to experiment with a 'sniffer' removable tail-pipe to see what the petrol mixture is doing on each bank of the V6 :D May be more informative than the slow-to-react CO mixture analyser I have.

Speedo shaft seal at the auto gearbox has now been renewed (thanks QRG), and the internal diameter of the old one was obviously worn large so hopefully that's a leak fixed! Access is limited to tap the seal back in, so a small socket and the side of a hammer tappity-tap about a hundred times got there in the end.

I'm going for 'unimpressive photo of the week' award: My new improved dashboard warning lights are fitted :D I am very happy with them in fact - particularly that the 'P' warning light (perhaps unique on a SE5a Scimitar) works very well 8) Boy with a new toy.

Photo shows them all switched on, including the radiator fan warning via the manual over-ride switch. Left-to-right in the photo: low fuel; brakes (handbrake and/or fluid level); rear fog light; radiator fan; heated rear screen; park/neutral gear position. Not sure of the light LED colours, but there wasn't a choice except for the symbols. Spent two hours just wiring these six lights in ! Ridiculous; then spent another hour tidying the rat's nest and also repairing the intermittent handbrake warning switch. Was a nice sunny day, so it couldn't be wasted indoors :wink:

I next need to bleed the oil pressure pipe to the pressure gauge. I had what looked like low pressure some time ago, but later realised that there were air bubbles in the hose from being disconnected; just like brake pipes I suspect pressure doesn't fully reach the gauge when there is air in the pipe :shock: It's just a case of running the engine without the pipe connected to the back of the gauge until it runs bubble-free, then screwing it back on. I expect a mess; I am good at that.

Like the lights (although I can’t see the point in a Park light) - I’ve never needed to bleed an oil gauge pipe.

IMHO the air bubbles will compress to the same internal pressure as the oil that is compressing them, so ought not affect the gauge.
I hope I'm wrong, so good luck, get ready to catch lots of oil though!

I reckon you are dead right; at the time of typing it felt wrong about the oil & air fooling the oil pressure gauge but I couldn't quite get why. The brakes analogy isn't right, as it's the squashiness of the air in the pipes that makes you run out of pedal-travel - once the brake pedal & pads are stationary, the pressure will be transferred to the other end of the pipe. Apologies for the misdirection :oops: Must remember my O-level Physics better :?

That begs the question - what do you think is wrong with your oil pressure gauge readings?
You know there are lots of willing helpers (metaphorically speaking) out here with years of experience... :)

Yes, the forum members are a treasure trove of knowledge; I shall change the oil filter to the well-respected ford one before I consider there being a problem with the gauge or engine.

Worst case with air bubbles is you get a bit of damping. If the pipe was black (like the original) you’d be none the wiser 8)

Well, a momentous day :P I drove the car On The Road :shock: I first fitted the dashboard and indicators stalk - plus as a luxury - the steering wheel.
Even with my petrol priming bulb, it takes ages of churning to start it up, then subsequently it starts instantly; this is lucky because I think the mixture is far out and the engine stalls on some tickover-to-drive transitions. It went about half a mile, all in first gear (automatic 3-speed) or reverse, around a couple of mini-roundabouts and back onto the driveway. Exhausting :| The tyres feel a bit 'square' (original 30-yr-olds) and something scrubs/rubs on full RH lock. Otherwise, smelly, noisy and fun :D Rev-counter has given up & the indicators tell-tales are all but invisible and inaudible; wipers go from left-to-right and the rain stays where it is :lol: Some work still to do!
