everyone that I've had is 12V. One battery--- but there may be different circuits in the trucks that use a different voltage. What is the problem you are having? Darin
Just a note for the record. All of these trucks are 12 volt. If you are reading a lower voltage across any circuit - assuming a healthy battery of course - it should be one with some type of variable resistor for gauges or dash lighting.
Thank you everyone! This "site" has been invaluable! First of all, for anyone who has never owned a "mini" and secondly for complete neophytes like myself!!!
