one question about big 3

As far as I know you should always ground the battery to the chassis. The engine also gets grounded to the chassis as well.

 

Why dont you want to use the factory spot? Just remember that the automaker chose to have 2 different grounding points for a reason. What type of metal is that alt bracket made of??

 

This is for the battery ground? Isnt there a small wire coming off the negative battery post to the chassis (fender).

 

forgive me im kind of lost, are you doing the big 3 and the wire you got is not long enough so you are trying to find a new place to run the ground wire?

 

Why dont you just go and buy some more wire, its only like 10 or 15 dollars at the most. But I would not run it that close to the exhaust, the insulation is not high temp and will probably melt. Where does the wire normally go to?

 

Well if I had to choose between those 2 spots id pick the alternator, at least it wont melt. Just make sure the area is very smooth, that metal looks very porous.

 

yea thats cool to start with but in the end you want it very smooth, the smoother the surface the more contact it will have the better the ground.

 

no its not that bad, just remember that power wire is not heat resistant like say spark plug wires are. Just wrap some type of insulation around that area of the wire and zip tie it away from the exhaust so it does not come into contact with the manifolds.

 

ThaT would be cool, just zip tie it to something to keep it from touching the manifold..
