Relocated battery wiring.

FCM, im in need of some wiring knowledge here.

Im currently running a oddesy PC680 battery located in the hatch. currently I have it wired using 4gu wire from the battery to a distribution block where it splits to a 4 ga wire to the starter and 8 ga to the engine fuse box. the battery is grounded to the chassis via the spare tire hold down.

I believe ive been having charging issues with car as ive been having starting issues on known good components. so after reading this link on hondata’s website, ive decided its time to rewire the car in a way that copies the oem setup.

my plan is to join the 2 cables at the battery terminal. from there they will run up to the fusebox and to the starter and im also going to run a cable from the battery to the to the transmission ground. now this leads to my question.

what gauge wire would you recommend I use. will 8 gauge wire for the starter and ground provide enough power with as little resistance as possible?? or should I run 4 ga as I am now?

any insight I can get here is appreciated

Run the 4ga from batt. to the starter motor, run an 8ga from the starter motor to engine bay fuse box, run a 4ga ground from stock chassis ground location to stock engine location, move the batt. ground, [4ga] from the tire hold down to a seat or seat belt bolt, even a shock tower bolt will be better.

Splitters, [“distribution block”] add a lot of unnecessary connections and that adds resistance. 94

:salute: thank you:up:

Since were on the subject. ive always run power ground wires up the opposite side of the car in my stereo setups based on eliminating feedback in the speakers. but since I could care less about that cause theres no system in the car. Can I run both 4 Gauge cables up the same path to the engine bay or would this lead to other problems?

You should be grounding the batt. to the cars chassis as close to batt. as possible not running a ground all the way to the engine bay. 94
