i am going to go get a 130 amp alternator for an explorer and put on my ranger.....will i need to upgrade the alternator to battery power wire since my ranger only has a 95 amp alternator? or will it be ok to run the 130 amp alternator on my stock wiring for a while...or will 8 gauge power wire be big enough for it?

 

i just called around and the largest wire i can get today is 6 gauge wire.....would this be large enough? i have a 150 amp inline fuse....is that large enough for the 130 amp alternator or do i still need bigger?

 

You should be ok with the 130 amp alternator on stock wiring, any more than that like the 175 or 200 I would upgrade the wiring.

 

cool......what gauge is the stock wire....i may go ahead and get 6 gauge wire just to upgrade.

 

I thinks its 8 awg.

Car audio shops should have 4awg on the shelf in bulk.

 

all the car audio shops around here wont sell it unless it is in a kit........i dont need an amp kit for $70......

 

Go to any welding supply shop and you can get as big as 0 gauge for $0.99 a foot!

Welding cable doesn't transmit power as well as car audio cable. The more strands inside the cable, the less voltage drop you have.

 

More strands = more flexible.
