My car has recently started to drain the battery over a period of three days! I’ve tested the battery (760 ah) which is three years old and tests as good. The charging system seems to be AOK when tested. I’ve isolated the circuit responsible as that protected by fuse 7 in the under-bonnet fuse box. Any ideas?

      It is necessary to measure the leakage current on a non-working car, eliminate a strong current leak. If everything is normal in terms of electrics, it is probably necessary to install a known working battery and check it in the same way within 3 days.
