Mark, the carb on that Olds is not side draft--the air horn is at 90 degrees to facilitate use of an oil bath air cleaner, just like Packard 12s. Copyright 1995-2023 eBay Inc. All Rights Reserved. True enough, but I always try to help if I have any ideas. then devide the amps into 6 v and get the ohms. A voltage divider circuit can give u the 6 voltage dc o/p from the 12v dc source.and a voltage divider circuit is made by a voltage source with a series connection of two resistance but remember the resistance value should be same ..for example let R1=R R2=R V=12then from the voltage divider rules we can say that Vo=R/2R *12=6V More answers below Devide the rating in watts by 6 volts and that gives you the amps that the light draws at 6 volts. Your 6 volt horn will be fine connected to the 12 volt system. EDIT: I just reread the thread, and see you have electronic gismos plus a 12-volt conversion. For detail calculation and formulae search for 12v to 6v step down converter article from search box in the menu.
