Default Higher amp. alternator

I have an 05 dodge 1500 5.7. The issue I've been having is that everytime i'm at a light or complete stop and hit the accelerator the lights on the gauges and radio dim a little sort of like a flicker and when I let off they stop. But it will only do it in the initial take off. I've also noticed that the drvier side headlight bulb(HID) will do it also. Battery is new and alternator is charging at 14.33v. Could it be possible that I need a higher amp. alternator?

Unless you have a major sound system, the stock alternator should flow about 110 Amps (it's rated at 130A). I could see a potential issue if you had a loose battery/ground connection, but the alternator should be fine. I'd head to you auto shop and see if they can do an alternator test to see what it's putting out. If it's dropping or very low output, then your alt is on it's last legs and should be replaced.

any good auto electric shop can BOOST the output of an alternator
if you are running a lot of accessories, audio components, extra lights, etc. you could buy a 200 amp alternator for about 5 or $600
they also make smaller pulleys for alternators, making it spin faster

if your alternator is found to be working properly, you could look into something like this http://powerbastards.com/proddetail....=Fitzall%2D220

I'm with Kurtis on this one. Have the alternator output checked and make sure all connections are clean and tight.

The other thing to think about is the bushings in your alternator may be on their way out. When this happens, your alternator may actually convert less AC to DC, resulting in a lesser charge to your battery. I agree with the other threads that you need to have your alt checked to see its output at idle and at higher rpms. One other thing is ensure your alternator belt is tight. If it is loose, the same effect can occur - less output at higher rpms due to belt slippage.

God luck.
