I recently was high bidder for a NOS, 6 volt, Hobbs meter. I served my apprenticeship at Stewart-Warner so what can I say? Just could not resist after seeing the old familiar face. I want to put the meter in the panel of an aircraft I am building, said aircraft has a 12 volt system. What I dont know about electronics and electricty would fill a library so how do I get from 12 volts to 6 volts? Seems I remember when we used to convert the old VW beetles to 12 volts, we kept the 6 volt starter, changed the lights but kept the windshield washer motor 6 volts. How did we do that? Anyway, all help will be appreciated.
