Hey guys. I just relocated my battery into the trunk. I ran my wire(4gauge) through the fender and tucked under the side skirts to the rear trunk. Use my Strut bolt as my (-) . It starts up but its weak and the battery is fully charged. I also keep on blowing 80 amp main fuse. So far im guessing my wireing is loose and jump. any ideas?

Did you scrape the paint away so you have a good ground? From what I read, 4 gauge is on the small side. I'm currently relocating my battery and I ordered some 0 gauge wires.

-luong. · 06-23-2009, 01:04 AM

Thanks

there might be a pinch in the power wire, or tear in the insulation.
I would also suggest thicker wire. 2 guage min.

jeremy242 · 06-23-2009, 08:00 AM

Yeah i used 2 gauge and i have no problems.

*DALAZ_68* · 06-23-2009, 09:21 AM

i also suggest checking the wire harness in the engine bay, could have possibly tugged to hard and pulled a grounded wire...CYA my friend...u have to CYA

I would upgrade to at least a 2 gauge wire and run a 100A fuse as close to the battery as possible.

duballstar37 · 06-23-2009, 09:42 AM

Yeah I ran 0 gauge. Your ground sounds iffy too like stated above.

tunersedge · 06-23-2009, 09:49 AM

run 0 gauge to and from, thats the CORRECT way to do it. Check and re-check grounds if you still run into problems.

waterboy · 06-23-2009, 10:07 AM

why did you do this"through the fender and tucked under the side skirts "
you should go under your carpet

slider2828 · 06-23-2009, 11:19 AM

Not a good idea to go outside the car.... especially positive is a really bad idea....

tsi_guy619 · 06-23-2009, 11:26 AM

dont run wire on outside....it will be bad if you were in a crash or something...run it inside....under carpet and through the firewall

-luong. · 06-23-2009, 12:22 PM

Im going out to find some new wiring. ill run the battery uner the carpet this time and see how things work out. thanks guys

I ran a 4 gauge wire when I relocated my battery and it did the same thing you said at start up (weak cranking). My friend relocated his but he used a 2 gauge wire and his starts up perfectly every time no delay or slow cranking. I eventually took out my relocation setup and bought a Miata battery works perfect for me now no issues!
