Nothing goes to the starter, where the hell did you get that from.
It would be ideal to run a ground wire from front battery - to rear battery - just like you do with the positive. (assuming the batteries are the same otherwise you have to isolate them)
IF and only IF you have done the big 3 (which you should have) it is possible to ground the rear battery to the vehicle. But if it's not a unibody car, it has to be to the frame not the body. |

i have not done the big 3 because i don't have a bigger alt yet.
i think i found my wiring problem
.
i didn't mean starter. i was talking about the starter battery. the 1st battery.
hope my stock alt will hold up with both of these batteries....
if not then ill have to buy a new one 
u guys don't have to tell me that i need a bigger alt because i know i do.
its a 90 amp alt powering 1600rms
but i don't have the other amp in yet so it will be alright for now |

Just don't ground to both the battery and the chassis. |

If you have not done the big 3, do NOT ground that 2nd battery to the chassis |
