thread split off the HT 6v Charging System w ground thread. Okay...I am trying to figure out a variation on this system. I need to because I have a Sturmey Archer hub dynamo and a led headlights /taillights that are designed for the dynamo. HOWEVER, I also want to power a 6 v horn. I have a 6v rechargeable lantern battery (lead acid). Finally, I have a kill switch. So far dynamo is soley connected to the lights. The kill switch comes from the engine (I assume the "white wire ", yet it is not white. Neither the honr nor the battery are connected to anything yet. I have made a rectifier in case I can use the dynamo to charge the battery. So...what's the best way to set all this up? Possibly leave the dynamo to the lights? Charge the battery with the white wire? Could a big capacitor take the place of the battery if it is just for an occasionally used horn? If the battery is used, will this act as a kill switch? Best to just charge the battery at home and leave the white shire and dynamo alone? ( not my fav. option..... too simple.) Tie a cat to the handlebars and pull it's tail when I want a horn? Heck, I'm not even sure I have the right wire on the kill switch...but it does work. Thanks fo any help...especially very simple help.
