Officially, hello, from a previous TVR owner and hope I can be forgiven (eventually!) from straying the fold!??
My first serious post here on SCH is, what is wrong with the alternator/charging system on these cars? Is it a TVR 'bodge' whereby the alternator only charges when the engine is revved to 2k rpm due to using a mixture of gauges/alt/loom, or is there a problem with the diodes on my alternator?
How many of you with S3's have the same issue?
Have searched all the posts on here relating to this I can't get a definitive answer whether it is a 'common prob' that all the S3's suffer from or is there a fault with mine? Yes, I know it's all about resistance to 'excite' the b*gger to charge but I can't believe this was accepted as standard when these cars were produced?
When I had a 2.9 EFI Scorpio back in the 90's I don't recall having this issue!
And all the cars that I have owned from way back in the dark ages of the 60's never had an ignition warning light illuminated without there being an obvious problem, usually a thrown belt, giving me an excuse to wrestle the tights from the 'good lady' passenger!!
So (dreadful way to start a para, I know!), what is the answer???

Considering the cut-in speed of an alternator is approximately 1000 RPM give or take a bit, think now about the ratio crank pulley size to alternator pulley size, the alternator is going at some good revs even at engine tick-over
I doubt very much that the problem is a standard factory build problem
Quite so, that's why I believe there is a problem with my alternator although it charges once revved! Just asking the question as a few have said this is 'normal' behaviour????I doubt very much that the problem is a standard factory build problem
