Presumably can still buy very cheap small analogue multimeters. Although these can be easily damaged on the seldom used ohms or amps range, not completely reliant on batteries, not so confused by erratic contacts, spikes and spark radiation etc, and generally less confusing for amateur work on older autos. Too inaccurate for setting voltage regulators (and perhaps even for monitoring battery chargers) but we dont have regulators!
Much can also be traced with a small bulb on leads.
For Seven owners it is worth the effort to establish a full grasp of the ignition and charging circuits.
When messing about with the engine stopped, or possibly with a dud dynamo, it is important that the cutout is not brushed, bumped or prodded to close as it will lock and drain the battery and possibly cook the dyanamo. Can pull open or disconnect battery to release.
Igniton switches (like synchro hubs) should only be dismantled under a sheet in the middle of a large bare room with tight floorboards!
