da: dual battery hookup
This should not be a difficult task. First some information is needed. Are the batteries 6 volt or twelve volt? Is the long cable red in color? Is there a short cable with 2 cable ends? Look at the starter closely and look for any voltage information. Look at the alternator for any voltage information. It is difficult to make a long distance decision with out all the information. Are the batteries the same size and amperage? Any other battery cables in the battery area?
Send more information..... Frank
