dual battery hookup

[frank-id]

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

Just hook them up opposite of what you are doing now.
