H.O. alternator swap

H.O. alternator swap/Dual alt kit install pg.2

This will probably be my only tech write up I do because it deals with electronics. Anyways, my electrical system could not hold the necessary voltage so I decided to upgrade my alt.

Iraggi 300 amp alt


OEM on the left/new alt on right


Pic of serpentine belt lay out


Pic of the Serpentine belt tensioner on the far left



Alternator bracket


New Alternator installed


tools used were a 15mm/10mm/5/8" socket

- 15mm for depressing the belt tensioner.
- 5/8" for removing the mounting bolts
- 10mm for removing the positive nut on the alt.

From start to finish, the swap out took an hour and that included running to autozone to pick up a socket and I am a novice. When/if/even if you don't upgrade your alternator, it is recomended that you upgrade your charging leads(Big 3)(the red 0 gauge wires you see) if you run a heavy electrical load.

Why wouldn't u just use a kinetik stereo battery? They are an alternate solution to changing the alternator.

Did you change the belt?

No response yet on where you got the alt ? I am running 4 dry cell batteries under the hood ( a little overkill I know but I was boored and had 2 yellow and 2 red tops ) and that alt would be perfect for my 2nd alt. If you can lead us in the right direction im sure we would all appreciate it.

And a high current battery doesn't mean it'll put out a higher charge

Thanks Steve,

And no, I didn't have to change the belt.

do you notice a difference?????

 

[gibsonm21]

Yes, I see a huge difference with the new alt. Before with the stock alt, I did not have the current to charge my batteries and play my system at 3/4 volume. Now I can play at full volume and not see my volt meter drop.

The only caveat to the alt is its the lower grade series and while I see more amps at idle than my stock alt, If i crank my system at idle, my voltage will drop, but at 2k rpm, I stay at 14 volts.
