Hello again guys and dolls! I just got home from work, stopped by wal-mart and got myself this bad boy for $15 bucks:
^it's a voltmeter that simply plugs into your cigarette lighter - a great alternative to the 52mm voltmeters in which you have to install into a guage pod.
This voltmeter convinced me that there wasn't anything wrong with my alternator. It's just the voltage regulator in my alternator that isn't in sync with my charging system (no big deal - just annoying flick of battery light once in a while). After observing the voltage changes on the voltmeter, I noticed at the point when the battery warning light starts to flicker (for a millisecond), the voltage dropped down to 12.5 volts! This is odd considering the normal voltage is SUPPOSED to be 13.5 when the car's engine is on. But since this is a high output alternator, it rapidly charges the battery full and the voltage regulator kicks in and limits current flowing into the battery so it doesn't overcharge (thus the brief flash of the battery light). So after the voltage regulator kicks in and makes the battery light flash once and turn off, the volts drop down to between 12.5 - 13.0 volts until more load is on demand. Once I turned on my A/C & stereo all the way up, voltage regulator sees this (doesn't flash light this time) and bumps up the voltage from 12.5 volts to a healthy 13.8 volts! Long story short, my efforts in installing a HO alternator wasn't wasted at all

I highly recommend this voltmeter if you actually care about your electrical system - it's a must have! I even sacraficed the plug in which I use to power my radar detector and put this voltmeter in its place.
I'm one happy camper for now
Let's see in the longterm how this high output alternator treats me.
