ZZP Free Mod
This mod is haises the voltage by a half a volt http://www.zzperformance.com/grand_p...les1.php?id=48
Has any one tried this and where should I measure the voltage to test this. |
This mod is haises the voltage by a half a volt |
...raises...
looks like a waste of time to me... not that some convincing wouldnt work |
OK, so if you add the silicon diode, which has a forward voltage drop of about 0.6 volts into the reference wire, I'd imagine that it could raise the output voltage of the alternator's regulator by about the same amount. My question is...to what purpose? What is this supposed to do?

Works wonders when your on the edge of maxing out you injectors. ;)

What I was thinking is that I have all that is needed for this mod laying around my room. I guess what I am figuring is if the alt is putting out ~.5v extra the amperage would also increase making a 140amp become a ~144amp. So when I finish my stereo and have powered back speakers I will not be as likely to have the lights dim on me.
If What I am thinking is totally off tell me or if you have any ways for me to test this I have a Digi multimeter. I am mostly interested in if it works and by how much ect. silicon diode, which has a forward voltage drop of about 0.6 volts into the reference wire, I'd imagine that it could raise the output voltage of the alternator's regulator by about the same amount |
A silicon diode has a constant voltage drop when forward biased, regarless of voltage applied as long as it is above the .6 or so volt. The voltage across a resistor will vary depending on the voltage applied and will sort of defeat the idea of having the reference voltage to begin with. Withoug digging more into the regulator circuitry, whether or not it will have a similar increase in current is unknown.
If you're going to do it, I'd suggest sticking with the diode. It is not that expensive. Be certain that it is installed in the direction they show in the picture. Diodes are polarity sensitive so they will block the voltage if put in the wrong way. |
I was thinking about doing this but.. I only have one wire on that plug for the alt. Do I just use that one?
|
Unless you know for sure what that wire is, I wouldn't recommend just tapping into it. You may not like the results. You could raise all kinds of havoc with your electrical system. I'd wait until someone who has the wiring diagram can say what that wire is.
