The 6/12 batteries do work but it really does not solve your problem...you are just treating a symptom. Think if it as going to the dentist with a toothache and a cavity and having the dentist give you an asprin for the toothache and sending you on your way. Your toothache is gone but the cavity is still there. You need to either stay 6-volt or switch to 12 volt. I build 6 volt alternators if you want to stay original but still have the bright lights and good starting. I wiill also help you make the conversion to 12 volts if that is what you want to do. Better yet e-mail me your address and i will send you a copy of the Alternator Gazette which explains all of this in depth so you can make a decision based on some facts.....thanks Randy Rundle grin grin eek eek
