I moved the battery to the back of the hatch on my crx. im using 4 ga wire for power and ground. my problem is that the battery dies overnight, in the morning when i try to start it, the battery is dead. Now i didnt have this problem when the battery was on the front, on the orginal location. i have 4ga ground from the frame to the tranny like the orginal wire, and the ground in front on the head.
i think its a ground issue, should I wire a ground from the back to the front. or should i run more grounds the engine. And no nothing stays on over night all my amps and radio shut off.

 

are you sure it isn't a charging issue? with the alternator? i've reloacted my battery in the same manner and have had no issues.

 

I can also be almost 100% sure its a charging issue,

 

well wait, so the battery is fine all day if you drive it every now an then? it just dies if it sets for a long period of time?

 

it shouldnt have anything to do with the relocation, its something drawing power when the car is off.
Bad stereo wiring maybe., alarm?
I have something in my dash draining power (manually disconnected alarm and stereo, still -1.0 amps drawn)

 

yeah i have that same problem to. well i didnt relocate the battery to the back but overnight the battery drains out. i took out the whole alarm system and it still happends. my hommie from honda in torrance told me 3 things to check out:

check for bad grounds
have the starter checked out at autozone or pep boys
have the alternator checked out at autozone or pep boys

they check em out for free. when my engine doesnt start i have to use my battery jumper. just my two cents if it means anything

 

i didnt have this problem today this morning, weird?
i think the battery wasant charged enough. i will se tomorrow to see what happens
