Thanks for the replies. No the battery has just been fully charged. The car turns over easily.

It doesn't particularly matter, anyway, as it's my old car and is set to be scrapped fairly soon. I was just interested to see whether it would still run, that's all.

I probably won't get around to sorting it out, it's only likely to go for scrap value, anyway. It's just that I know electrical systems on cars are so very complicated today I wondered whether removing the radio would prevent the car being started. Apparently not.

Thank you once again.
