correct way to wire 2 agm batteries together

[akuma4u]

Hey

Im getting told to redo my wiring for my 2 agm batteries..

i thought I had it wired up properly but according to one source he is telling me the way i have it done will do nothing.

The way i have my 2 agm batteries wired up is like this:

agm under hood + runs to the + to the agm in the trunk

agm under hood - is grounded to frame in front

agm in trunk - is grounded to frame in back

is this correct?

my friend is telling me to run a long ground wire between the agm - in front and agm - in back.

so... which is the proper way???

You can ground the battery in back to the strut tower or frame, or if you prefer you could run a wire from front to back for ground, but it honestly does not matter as long as the loop is complete

Tell your friend to stick to coloring books.
