ALT. NOOB

[blue fury 3]

I need a new alt cause im about to put 2k rms in my car. Already found one from excessive- 200A. Did the math for the amps, should be good. He includes diff. guages of wire, I knew I would need that but what guage? 2? He says that it should bolt right on, but is there anything else I need? What about fuses and their ratings?

Since this isnt in my area im just going to have my mechanic put it in but I want all the parts ready to go cause I dont think his parts are as cheap as excessive's...

make sure he sends you a pully with the proper teeth or ridges. run a big 3 in 1/0ga wire and run 1/0ga wire from your alt to the batt. you could run a fuse in between the cable from the alt to the batt. some do it some don't. it's just a to be safe thing.

wouldnt that be kinda pointless since there is power coming from both ways?

makes sense to me cause on my other car, it would only start like half the time cause the battery would give enough charge even though it was a new batt. Took it out of the trunk, mounted it in the orig location, upgraded the engine and battery ground wires and it worked. If only I drove it more often... Thx fbi

Do you have special fuses that only let power transfer in one direction?
