I was becoming concerned. We had not had this enquiry for several months!
Analogue voltmeters are often in error, but digital ones go haywire near running engine. The coil should draw about 4 amps, half that running. Presumably the 10 amp discharge is with lamps on. Even the later dynamos should not be adjusted to more than balance 10 amps.
When prodding the cutout beware not left locked down.
Has the battery ever been fully charged? For all unmodified Sevens and especially cars not in regular use battery optimum maintence is a bit of a trial. especially if sealed calcium grid battery. A modest summer charge rate backed by a permanet bench smart charger probably ideal.
Do you have any battery charger? The ideal bench charge ritual depends on the charger capacity and the type of battery.
