Can the Voltage Regulator be replaced on a 2003 Chevy Suburban without getting a new alternator?
No, because it is built into the alternator.
How do I test the alternator on a 1999 Pontiac Sunfire?
Connect a voltmeter across the battery terminals without engine running reading should be around 12.8 With engine running reading should be 13.8-14.2 if you are getting these numbers alternator is charging battery
Why is the battery light on in my 93 Crown Victoria It has a new battery and a new alternator.?
Since you replaced the battery and alternator, you must have had a problem before. Did you run a voltmeter on the battery while the engine is running? Should have around 14 volts. If you are getting around 14 volts, you can assume that the lite might be faulty. If you are getting say, 12 to 13 volts, then the alternator might be faulty, yes even sometimes rebuilt ones. Check all the wires to make sure there is good contact, also if you still have the problem, then you might have a broken wire ( somewhere ). Good luck
Lincoln mark viii 98 you replaced the altnernator and now your car wont run unless you charge the battery yourself what is the problem?
With the engine running, test the voltage of the battery using a voltmeter. You SHOULD be getting anywhere from 13.5 to 14.5 volts if the alternator is functioning properly. Turn on the headlights and rear window defroster and make sure you can hold the voltage level (you'll need someone to keep the engines at about 2000RPM's. If the alternator isn't producing sufficient voltage, you either have a faulty alternator or the replacement was not connected properly.
Why is your battery not getting charge when the alternator tested good twice?
Loose or corroded connections or the battery has a dead cell and will not accept a charge and must be replaced.
Fuse alternator 1995 mercury mystique?
I have a 2.0 1995 Mercury mystique the battery charge light was on no output on old alternator. Replaced alternator No output from new alternator "charge light out" (wiggle test wires& re-check wires) at alternator *still no output* is there a fuse that could be the problem or just another bad alternator... I would check the alternator plug before getting another alternator, it may be bad. And is a lot cheaper to replace.

You have replaced the battery and your car started right up one time and now just clicking when you turn it over?
The alternator is not charging the battery, therefore, the coil is getting it's charge only from the battery.
Alternator and battery have been changedIs there another reason why the battery gage would still read low?
Ignore the in-dash gauge. Find a good, well calibrated voltmeter, start the engine and test the voltage at the battery. If you're getting somewhere near 13.5 Volts with the engine just off idle, don't worry about it. If it's UNDER 12 Volts, you probably don't have a connection from the keyswitch to the alternator.
