David, if it's any help ( and I appreciate my RP has a slightly different set-up. On starting the engine with summer setting selected, the ignition lamp glows until I raise engine revs to a certain level whereby the dynamo output is high enough to cause the voltage regulator to close and the ign lamp goes out. On winter setting the dynamo output is higher so it takes less revs to generate the same output. However until the regulator trips the ign lamp does get brighter until the cut- off occurs. I use a 12v bulb. Dynamo output is set to give max 8amps on winter. Hope that helps.
