Re: alternator replacement

David,
Do you have a digital multi-meter?
They can be very useful.
If you check what the actual voltage is
at the top lug of the alternator,
while the engine is running
it will give you a better idea what is going on.

If you go back and read the test results again over the years, you will see the go the figures go down over the years, due to aging wiring with corrosion and increased resistance, and go backup after the wiring mod, and up even more once a new battery was installed.

How old is your battery? That is also a major factor.

Wiring is the most important part of the modification. I just happened to be using a new high-out alternator at the time and developed a cleaner, simplified look by removing unnecessary wires


Before this, the 3-wire upgrade was done all the time of increase current flow, using the stock alternator. In fact, I did 3 of the original alternator wiring upgrades in the same day at the 10th Anniversary Meet in Lafayette back in 2002.

That was the simplified one of adding only 3 wires. No fuse, no cutting or removing anything, just adding additional wires to improve current flow. In the early days of the mod, members would pick up around 2V more than before. lights were brighter, started more quickly, etc. New wires, fresh secure connections and better grounds make a lot of difference.

That original mod, with detailed instructions and photos, can be found HERE

POS 4 gauge from alternator post to Battery positive
NEG 4 gauge from battery negative to engine
NEG 4 gauge from battery neg to frame ground







For a better understanding of some of this read the Alternator 101 article HERE

Re: alternator replacement

haha wow, talk about where are they now?? I forgot that guys name, but I remember he had the white svx with steveby's front bumper. He was one of the first at that time. Man, 10 years ago??? I remember that alternator issue, didn't it first go out after the dinner?

...I am also envious of those functioning hood struts!

That's the infamous Zeppelin eyeballing the camera. He stops in every so often.


How can you ever forget these: Before I could introduce him to the "Dremel-style" of detailing, he had already discovered "Krylon-style"

it's giving me 14.6 which is pretty good i guess

based on your wiring pdf
2008: 14.3
13.4
13.2
12.4
12.0
2009 after alt and 4 gauge wiring...
14.3
13.8
13.3
12.6
12.1

but i understand that you upgraded an already upgraded wiring system and that explains it...
