I have a 1266x and its been sitting in the corner for at least 12 years.... I know!! I removed the battery cover and it was not pretty. Nothing was identifiable...no survivors! After steam cleaning, pressure washing and disinfecting, I have a black and red wire coming out of the battery box. The only question I have is.... is this thing 6 volts or 12 volts.... I have 8 dead battery bodies but all wiring and metal pieces parts are more or less, hash..... The plastic battery holders will have to be replaced as well as the the connector... I'll figure all that out when I find out if its 12 volt or 6 volt. Thanks... Rockfoot, SC
