4 1/4-litre Bentley - Electrical.
There have been several failures of the dynamo not charging, due to a fault in the circuit to the ignition warning lamp. The twin cable which does not look like our own has been shorting on the holding down screw of the regulator. The wire has been pulled too tight and destroyed the covering as per sketch.
