Welcome Adam to you and your HF turbo,it looks lovely.
I used to own one back in the mid 1990's, great car.
suggest you send a PM to 'Andy D', Andy Deykin has a lovely HF turbo as well as other less exoctic Deltas and he has a lot of experience of them, he also bought my Workshop Manual off of me, so I'm sure he would help you.
If you've got electrics that don't work or play up have a look and clean up as many earth points as you can find, including checking the main battery earth strap, as these sometimes look ok but can throw up a number of supposedly unconnected electrical faults, in fact it's probably worth changing anyway.
What's the bodywork like at the top of the tailgate aperture, if you've got corrosion around the windscreen the chances are you've got it there as well, not easy to eradicate but well worth stopping in it's tracks.
Pretty sure you need blue antifreeze ,as for bleeding I have a fsint recollection. possibly wrong that there's a sort of rubber wheel that you turn on one of the hester hoses?
The reverse light switch is once again if I remember correctly is on the back of the gearbox, this may also just need checking for a good connection, if you're going to be removing rear light lenses look on ebay and try to find new red and white plastic screws that hold the lenses in place, these go brittle and break easily.
Coolant warning light, check lights also suffer from earthing problems.
I used to changemy oil and filter at 3000 miles and always used a good fully synthetic oil
in my case mobil 1, not cheap but worth the money.
don't forget to let the engine idle a little before turning off.
Think that's about it for now
