Let us assume that the internal voltage drop is not relevant any more then we see 46,2Vrms/1500ohm = 31mArms which is not a safety problem. Normal RCCB (Fehlerstromschutzschalter) are rated for 30mArms.
This means: There is no dynamo voltage hazard same as with older ignition systems for gasoline cars which produce around 10.000V but with very high internal resistance so that no significant current flow can occur. Modern ignition system are more powerful but still are only dangerous for people with cardiac pacemaker. There must be a current flow and especially during vulnerable period of the heart. Outside this period even lightning flashes can be survived.
