I got together with my friends from BBB Industries on this one, we managed
to put together a pretty comprehensive step by step on what to do if you
suspect an alternator issue. Take the time to go through these steps the
next time you suspect a bad alternator and you just may save yourself a
trip to the auto parts store.

Your vehicle's alternator is a vital component because it assists in
charging your battery. Test your alternator to make sure your battery will
continue to charge.
Step 1: Find the battery
Locate your car's battery, usually located on the left side of the engine
if you're facing the front of the car. If it's not there, check the right
side. Some cars even have their batteries under a seat in the middle of the
Consult the owner's manual for your vehicle if you can't find the battery.
Step 2: Connect at the voltmeter
Connect the voltmeter to the battery while the car is off. Connect the red
positive wire on the meter to the positive battery terminal, and connect
the black wire on the meter to a bare metal grounding source, such as a nut
or bolt on your car's frame.
Step 3: Read the battery's voltage
Read the voltage on the meter to determine how many volts your battery is
producing. Twelve is average, and if goes much lower than 11, you need a
Step 4: Turn the engine on
Disconnect all wires and turn the engine on and reconnect the meter to the
Step 5: Read the voltage
Read the voltage on the meter as the car is running. If the voltage with
the car running is higher than the voltage when the engine is off, then the
alternator is fine. If it's lower, your alternator needs to be repaired or

I enjoy the process of testing theory because you always learn something
new, regardless of the outcome.
Using a spark plug defouler kit, I install a "buffer" in between the
downstream oxygen sensor and the catalytic converter. Quite often,
frustrated car owners get the P0420 code for reasons other than a bad cat.
I have heard of people getting the code just because they removed the
converter and reinstalled it. It can also happen if you run your vehicle
out of gas etc... etc...
It is also common for car owners to get the P0420 code, replace the
converter, and both o2 sensors-- only to have the code come back after 1000
miles or so. This can be a very frustrating, time consuming and of
course-- expensive venture. Here is one way to resolve the issue. Good
luck and have fun!

Car Audio 101 - Alternator Tutorial
DIY with Mike Stiers
Back to Basics -- Car Audio 101
By Mike Stiers
So you've decided to upgrade your car stereo system? A great deal of
research and planning should go into this purchase since there is a lot to
consider. Do you desire a nice upgrade of your factory speakers, are you
looking for a Sound Quality overall of speakers, subwoofers and amplifiers,
or are you designing a vision-blurring SPL machine? It is important to make
a list of exactly what you are looking to replace or add to your audio
system so that you can prepare your electrical system for the investment to
Many people do not realize that their vehicles' factory electrical system
was not designed for aftermarket audio equipment. In fact, most factory
electrical systems can only handle an audio system of 600 to 1200 watts.
The lower end of the scale being the smaller vehicles and most foreign
rides, and the upper end being large trucks and sport utility vehicles. As
you increase demand, you need to look at upgrading your battery, alternator
and most importantly your "Big 3."
The alternator powers the vehicle, all components and recharges the
battery. A standard factory alternator ranges from 40 amps to 120 amps
depending on vehicle. When the alternator is under high demand or the
demand exceeds the alternators capability, your voltage will begin to fall
and rely on the reserve of the battery. Lets use a 65 amp alternator for
example in determining what aftermarket audio equipment the alternator can
sufficiently power. In perfect condition, your 65 amp factory alternator is
charging at 14.4 volts and is capable of supplying 936 watts. (65A x 14.4V
= 936 watts) Your vehicle requires 30%-50% of this to run and operate
standard vehicle components. If we use the middle, 40%, you are left with
approximately 561 watts for your aftermarket audio equipment. (936W x (100%
- 40%) = 561W) This 561watts is based on a 100% efficient amplifier which
we know is not realistic. Lets assume you choose an 80% efficient
amplifier, which is very efficient. If this amplifier uses 561watts and is
80% efficient, it will produce 448.8 watts for your speakers or subwoofers.
(561W x (.8) = 448.8 watts) Going beyond this point and you begin to tap
into the reserve of the battery. The result is a decrease in amplifier
efficiency and an increase in heat due to decreases in voltage and
increases in amperage. This is very hard on the alternator and amplifiers
in the system. By now Im sure you see why an upgraded alternator is vital
when upgrading your audio system.
DETERMINING POTENTIAL OF CURRENT ALTERNATOR:
Alternator Amperage Rating x 14.4V = Potential Wattage
A x 14.4V = W
Potential Wattage x (Maximum Potential Percentage Used to Run Vehicle) =
Watts Available for Aftermarket Audio System
Answer from Step 1 x (100% - 40%) = Watts for Aftermarket Amplifier(s)
Answer from Step 2 (100% Efficient Amp) x (Actual Efficiency of Amplifier)
= Watts that can be produced in current application
