Oil pressure gauge
Discussion
Well, apart from being locked out today by errant central locking, I noticed the oil pressure gauge going a bit erratic.
Ignition on it hits 90lb/in, start up it'll sit at 40 when running, suddenly it'll jump to 90, stay there for a while then drop to normal or flicker rapidly between the two positions.
At first I was worried expecting blown seals everywhere then realised it was probably an electric fault.
Any clues as to where to start looking first?

Agreed, but last night it was dark by the time I'd walked the dog, fed the bairn, sorted (not) a PC, fed the wife, cut the grass and then blew the tyres up. I knew my old Chimaera had no power steering and was lighter than this one.. tyres at 15lb on the front...
So this weekend I'll be under the bonnet (and possibly the dash).
Oh and going to BAR111...

Crawled underneath this morning, the single lead to the small dender is now cleaned and tight, am I right in thinking the large one above is for the guage?
There is a wire to a post & nut but on the ther side thre is a post with a male spade terminal but no wire and no loose wire any where, is this normal?

These bellows type oil pressure senders are notoriously unreliable and typically have quite a short life, common to Jag XJ6's & the like back in the seventies they were rubbish then & are no better now.
I've been using this cheapo EBay one with good results for a few years now:

You need to run an earth lead off the second terminal and make a converter lead to go from spade to ring terminal on the original TVR gauge wire, but these are easy 5 minute jobs.
More recently I found this one:
It's longer and more expensive than my cheapo one, but all reports seem to indicate it's the most accurate sender yet.
You could just buy an original sender from a TVR specialist, but there's no proof it'll be any more accurate or reliable long term and you'll be paying almost twice.
Actually in my experience the original wasn't well matched to the gauge anyway and gave unrealistically low readings, typically around 10 - 15psi (or more) below the true pressure.
I'd fit this one and have done with it.

Left this problem aside for a few weeks due to there non TVR problems but back on the case,
On the early engine, do I need the two terminal one - would the single terminal one earth ok through the body?
Well I thought this was going all to easily.
Old sender out, it screws into a brass adapter which came out with it.
New sender into old adapter, screws into engine, snaps adapter.................
Any ideas where I can get a new one please, off the shelf at an outoparts place or are they a special?
Thanks

Quick thank you to David Gerald, new adapter arrived and fitted yesterday. Back and running again.
BUT! Before with the old sender the oil pressure was around the 40mark, doing the usual dropping on tickover rising on higher revs. Only reason I changed was every now and again it flew up to the max, usually at lower revs, which I took to be a faulty sender.
With the new sender it sits at nearer 55 and drops slightly on revs....
Might put the old one back....
