Griffith ignition warning light coming on while driving
Discussion
If the alternator belt isn't broken, check the 100amp fuse under the car.
You'll find it in a little black box like this

I would suggest that your symptoms are that of a failing alternator. It could e the 100 amp fuse but gradual red light deterioration from flickering to solid on isnt how the blown fuse behaves. Go to any good garage near (or even halfords) and ask them to check your alternator and battery. Your alternator should be kicking out 13.5+ volts with the engine running.
Thanks everyone for your help, I didn't think it was a fuse but was hoping it would be as it's such an easy thing to fix. I have been told the pre serp griff 500 alternator is very difficult to fix or replace so I would like one stored in my garage even if I don't need it now, what's the situation ?
I really appreciate the knowledge you all have, it makes me feel much more relaxed about the TVR which I wanted for years but never felt confident enough to buy. I really like the grif as it bridges the old car experience with modern car grunt (and some) without all the driving aids that make it pointless, I feel much more relaxed about owning it because there are so many helpful people out there.
I have lots of plans for the car so will be reporting on progress as things progress.
Cheers Si

Try Tvr parts but go via local specialist like DG SPORTSCARS REDDITCH.
The one you want is probably this
https://tvr-parts.com/tvr-parts/part-details/tvr-e...
but depends on your specifics eg with or without power steering/aircon.

A local car electrics place might be able to refurbish your alternator. They can generally do it in a day or so, so maybe worth asking a local garage if there is anyone near you that does that sort of thing - or try a search using your area.

They will certainly be able to bench test it and tell you if it is the problem if not. They will also be able to test the output with it on the car. Google auto-electrician, call the likely results, and take the car to them, I would suggest. Will minimise your hassle. If they cannot repair the alternator themselves they will know who can locally.Jim
Ok ordered new alternator from TVR parts on Monday which arrived wednesday which is great, fitted it yesterday evening which needed one wire connector changing, seems to be working fine, noticed battery meter is reading slightly higher which also makes me think it was the alternator anyway. Drove it to work but oil pressure gauge now not working so hoping thats a fuse ? maybe from disconnecting the battery or something. water temp etc was all fine and oil level is ok so cant be actual oil pressure of zero
Thanks for all your help, extremely helpful.
will keep posting when can. Best regards Simon

May not be connected......in both senses.
My experience is of a late Chimaera, so could be wrong for your car, but on my car the oil pressure sender is at the bottom front of the engine near a chassis rail, with a one wire connection to it. The connector came loose (without completely falling off) at the end of a track day, when everything was hot. Drove out of Snetterton, onto the A11, looked down at the instruments, NO OIL PRESSURE !! actually, I only had oil pressure when accelerating, not when decelerating.
Luckily my TVR guy was also on the track day and was 5 minutes behind me, so he came to my layby and checked the oil etc and announced "sender connector, it's not a pressure problem". He's never wrong.....

Hi i have absolutely no reading on the oil pressure gauge which makes me feel a bit better as the car was used today for about 20mins without any other signs or a problem, if i genuinely had no oil pressure the engine would surely seize or least show signs of stress such as heat etc first.
Thanks for telling where the sender is though, i will order another one and then just replace it and check wiring etc etc at the same time. I am gradually changing all parts i can as i go along, so far starter, alternator, fuel return line. New alarm.
Next steps were going to be coil, fuel pump, HT leads cap etc.
just purchased a battery brain isolator as well to be fitted soon and will be ordering a hot start kit ASAP as had that issue already.
