Voltmeter Gauge
I have a 2000 Chevy Blazer with a charging system problem. I've replaced the battery, alternator...?
I was having intermittant starting problems, and had noticed that my volt gauge had dipped down to just below 14v. After loadbank testing, we determined that the alternator was not charging properly. I replaced the alternator, the battery (because the "+" terminal broke), and cleaned the cable ends. The volt gauge is now just above 14v. My Fluke voltmeter shows no-load charging at about 14.3v, but when I turn on all the accessories it falls to 12.8 - 13.5 at idle, and only recovers to 13.8v to 14v when the engine is above 2000 rpm. Any suggestions?
These values are fully acceptable.
Remember ohm's law.
It takes 1 volt to drive 1 amp through 1 ohm. So if the voltage is high in the system, the current demand is low. When the current demand rises, the voltage will decrease.
The TOTAL equation is AMPS over VOLTAGE divided by RESISTANCE and the whole package is WATTS. The wattage remains constant while any of the other three values may change.
If you are seeing 14.3 to 14.8 V at idle, with a fully charged battery, this is good. If the battery (or system) requires a higher current rate, the voltage could be as low as 13 V. As long as the charging rate is no lower, it will keep the battery happy.
Remember a fully charged battery at rest will show 12.6 V.
Good Luck

Digital Multimeters – A Step By Step Do It Yourself (DIY) Guide
Digital multimeters have indeed made the measurement of the working condition of any appliances very easy. Unlike, their analog counterpart, these can be operated by anyone with a little guidance just like the digital pressure gauge. And the best part is that they display readings in numbers, while the analog multimeters indicate the value with a needle over a scale. You can use them in gauging just anything, just by yourself.
Digital Multimeters to check dysfunctional bulbs- Step 1:
If a bulb is not working inspite being brand new, most of the time what we do is call an electrician. But not anymore... because now you can use any of the digital multimeters to check the same! For this you can check the resistance, or 'continuity' test function of your system. But before going for the same, first always disconnect the appliance from power source to avoid any accidents related to electrical shocks. Now, set the multimeter dial to Resistance (Ohms).
Digital Multimeters to check dysfunctional bulbs- Step 2:
After this, now touch the two test probes together (here it is important to note that the red one is 'positive', while the black is 'negative'. As soon as you do this, the OHM meter reading will indicate zero resistance, which means that there is continuity. A reading of zero indicates the circuit is closed and the circuit can conduct current. As, for your bulb- checking, take a standard one out of a lamp socket and touch one test probe to the bottom of the lightbulb, and the other onto the threaded side of the lightbulb socket. If the reading shows zero resistance, then there is continuity, and the lightbulb is good. On other hand, if it's does not indicate continuity then the lightbulb interior filament is obviously broken.
Follow these easy steps and you would become a pro in diagnosing electrical problems with digital multimeters in no time.
