Grounding/Earthing kits

[JohnBu]

my lights flicker and my stereo isn't that big. also my revs go up and down with the bass.

have you tried upgrading the power cable?

Black heatshrink is earth, so it's not really a problem. Probably not ideal, but not worth changing.

While I agree that the standard wiring isn't bad, I don't think it hurts to install an earth kit when you are significantly upgrading the battery.

I wouldn't bother changing them either.

but the installer who did definitely choose form over function.

Those ground cables are what, 4 or 2 gauge?

I highly doubt it would work better than a single run of 0 gauge from the battery to a good clean & short connection to the chassis.

myn dont flicker or revs jump ( speedo jumps but thats related to vibrations not power )

astra AHs must have pretty good grounds.. im still planning on upgrading myn but
