To help fredryck out, is there some adaptor or voltage stepdown, or something that we use to start the 226 using 12v? I know many cars I have seen have been coverted to 12 volt systems. Light bulbs seem to be the main thing to change of course. Sorry fredryck, but I only have personal experiance with the 6V system. We can even get new replacement parts here for the regulators, generators, and starters with no trouble. I will continue to try to find some help for you, until someone more knowledgeable than I comes along!
