Many years ago I had a battery go open circuit. That would have given a voltage of 0 if measured.
When I bump started the car in the driveway the result was spectacular. The side lights were on and they lit up very bright and illuminated the whole front garden until they blew. Likewise the ignition warning light lit up the whole interior.
The 3 brush dynamo tries to produce a constant current and in the absence of the battery the voltage went up to force 8 or so amps through whatever was switched on at the time.
