I bought a new Brawler 600 CFM Holley Carb with an electric choke. The engine has a CRT electronic distributor, and an alternator. I don't want to piggy-back 12 volts source to the coil because someone warned against this, the coil needs 12 volts steady. So I am trying to find another 12 volt running source under the hood. Thanks for your ideas.    1/8 cavman
