HELP NO POWER after relocating battery to the trunk

[starkos14]

relocated battery to the trunk and had power, went to start the car and the car shut off. no power, no accessory, nothing. the lights dont even work with the key out. my windows are down and its raining in my 240... any ideas, i checked every fuse i have under the hood and in the kick panel.

kinda hard with out seeing how its hooked up...the wires are hooked up to the correct terminals on the battery?(just making sure)Are you sure there is a good connection were you hooked the ground up to the car?painted surfaces don't make good grounds...

Maybe If you could go over how you hooked it up we could spot were you went wrong???

ok i ran 4 gauge wire from the positive terminal to the trunk, wrapped the area with electrical tape in the engine bay. i ran that straight to the battery. the ground wire i connected to the right rear strut bolt next to my rear speaker. i had power to the car. i went to start it and everything turned off

when the car shut off, my amp still had power running to it before it automatically shut off(which it waits 10 seconds after the car is off)

I don't like the connection in the first pic. I have my postive from the trunk hook up to the starter, and the stock positive wire I left hooked up to everything else.

also, bust out a ohm meter and check some of the smaller wires comming off the positive. some of them may be fusible links that popped.

ok, i put the battery back in the front and everything started up? i dont get how i ever had power and then lost it... is there a better ground in the trunk? im going to go fix the positive right now... and where can i drill through the firewall into the car? i have it ghetto rigged right now thought the fender in through the door

[sr20power]

i don't think it would be called "ghetto rigged" if you go thru the fender?

i'm about to attempt this next week, i have already looked to find a place thru the firewall...couldn't find one! i would rather run it thru the fender then passing it thru the driver side firewall. if you find one let me know.

the only thing i can think of...(since you placed the battery up front and had continous power)...is that the wire running to the back may be broke somewhere along the way.

oh and are you running some kind of fuse on the positive wire running to the front?

[starkos14]

ok i figured it out, some connection got cut, i rewired everything and it started right up. and i drilled low into the wheel well and the from the wheel well through the firewall where the passengers feet rest. worked well. the tire doesnt hit the wire either

[sr20power]

can you take any pics on where you drilled the hole into the firewall?

and a again....are you running any fuse on that line? kind of risky if you don't no?

i'll be doing mine next week

i can bet you money that if everything is correct... you don't have your negative ran properly up front in the engine bay... i grounded the motor 4 times to the chasis and the starter to the chasis as well.. grounding the block... transmission... intake manifold and head.... ... if that doesn't solve it...also i grounded the battery in 3 spots in the trunk... one on the tower.... twice on the rear chasis... and used 0 gauge .. keep the battery up front unless you have other plans or its for *show* purposes only...

btw that is the ****tiest connection i've seen in that first picture... atleast use a distribution block

[ichiban]

use zero gauge wire. my brother and i did an rb swap into his s13 and moved the battery to the back. initially we had used 4 gauge wire and couldn't get the car to start. change wireing to zero gauge and no more problems.

check continuity between where the battery cable comes from battery and where it goes to front
