I've got an electronic regulator, the dyno works without a (working!) battery but it blows speedo bulbs (especially but not only LED ones).
Very bright lights though! ;)

The regulator controls volts by regulating field current in the dynamo. IF it's adjusted too high you will blow small bulbs and maybe even bigger ones without a good battery in the circuit. You will also get excess depletion of electrolyte. Top up with distiiled water.(not acid) A dead flat battery is sometimes hard to get a charge started. IF it's been flat for a while it might be sulphated and may not recover. Nev
