chasis and motor have ground wires running to em, and hooked the starter up the exact way when i pulled the motor out of the old civic DX and tranny is grounded to the chasis.
when i got the car, the original dash was taken out and had a GSR dash put in, all the wiring was ran and everything.

i thought the terminals on my battery were bad, but lucky me i kept all the batteries from previous cars that i've owned. so i got a few laying around, and i make sure they keep a charge cause every other week i'll hook one up to my battery charger and check it to make sure.

but its also NOT just the motor, like my windows and sunroof and shit are doign the same thing!!! very sluggish going up or down, and what not.
