i have been told by many people to upgrade the 3 main grounds in the engine bay to 4awg wiring instead of having the standard 10awg wiring.

However i dont have a clue where the big 3 grounds are in the engine bay, can anyone help please!!!

Thanks

 

why do you think you need to upgrade the wiring ?

it was good enough for the manufacturer (Ford? Massey Ferguson?Ferrari?)

 

What car is it just out of interest

 

10 AWG carries 15 AMPS, whilst 4 AWG carries 60 AMPS, bit heavy really and as said not needed.

its a 1.8 escort gti, i was thinking it was a bit much upgrading them to 4awg and was just wondering if anyone else had tried doing something simular, obviously being told a lot of bull really den!

thanks for the posts guys!!

 

To be honest with you, the main starter cable is adequate enough, as its only really the starter that draws big current. The smaller ones are just there to make sure nothing is high resistance, and some sensors also require a good ground

Un-necessary IMO

 

thanks for the advice, i will probably leave it out!!
