thanks alot guys for your info. i didnt want to mess up my new charger and i wasnt sure how to run two batteries for a 12v tm. so if i do like HPBB said i just hook my tm up to the neg and pos on battery A and then i jump the pos and neg to battery B. then i just hook one battery up to the charger (not on the engine start bank). if i make the connections like this, the charger will still charge the batteries the proper way, correct.
thanks for your guys' info
