Battery Relocation Problem?

[yamifumis14]

I had to run intercooler piping so I had to relocate my battery. As soon as I relocated the battery to the trunk, whenever i turn on headlight or electric fan, my engine's rpm goes down and about to stall. Should I run some sort of circuit breaker instead of just hooking battery wire? Let me know what people has done or know about this problem. Thanks

1 what size cable did you run2 you should have a fuse or circuit breaker about 1 foot away from the battery

sounds like 1 the cable isnt a big enough gauge, or 2 your alternator/battery may be going bad... i have 4 gauge wire and it works fine, but when i do it again i will probably use 2 gauge, you can go to a parts store and most will check your electrical system for free to see if your alternator or battery are bad

I dont see why youd need a fuse inline since factory it doesnt but whatever makes you happy.

IB it the gauge of the wire though.

you put a fuse there for safety. think about an electrical fire in your cabin and yeah you'll think twice about not having a pretty cheap fuse in there.

how long is your ground cable?

probably about 3 feet? find a good part on the chassis to bolt it down to. It doesn't need to be long.
