Is possible to remove voltage regulator on a 2001 Volvo S60 without taking alternator off?

Yes it is.
Unplug the battery, disconnect cables from alternator. Unscrew 2 nuts (13 and 15mm) and 1 screw. Remove the plastic regulator cover. Unscrew 3 more screws and pull out the regulator. In d5 engines is useful to disconnect the intercooler pipe. You're gonna need a short philips screwdriver and probably less than 15 minutes.
thx

Buick lesabre new alternator battery will not charge?
Have you checked the fuses?AnswerMay be a bad voltage regulator. alternator is no good without a voltage regulator. that's what "turns on" the alternator.
Is there a voltage regulator on a 1984 VW Rabbit convertible?
Yes. It's inside the alternator and is replaceable without alternator disassembly. Remove two screws and the voltage regulator will pull out.
Can the Voltage Regulator be replaced on a 2003 Chevy Suburban without getting a new alternator?
No, because it is built into the alternator.
Can voltage reGulator be changed on a 94 ford escort without replacing alternator?
yes just use a torx socket to remove the 6 screws holding the regulator / brushbox unit secured to the alternator... remove electrical connections to the regulator first...easy!
Can you hook up a new regulator to an alternator without actually attaching it to the alternator?
Voltage regulators are often built into the alternators now, this wasn't always the case. Older vehicles had separate voltage regulators mounted on firewalls or the side of the engine compartment, wired in between from the alternator to the battery. The positive lead now goes directly to the battery from the alternator/regulator.
Where is the voltage regulator located on a 1995 Mitsubishi montero located?
Modern alternators almost always have their voltage regulator attached to the back of the alternator itself. Most often it is combined with the brush holder so you could say it's "built in", however that is not strictly true as it is removable without dissasembly of the entire alternator. Unless I am mistaken the Montero alternator is of this design. You should NOT expect to find an external voltage regulator anywhere on one of these vehicles. Hope this helped.

What is the purpose of voltage regulators?
Voltage regulators are intended to keep a certain voltage level, which is important for most electronics to run properly. Without a voltage regulator, if an electronic, such as a computer, receives too much voltage then it can fry the components.Controls output of alternator so battery does not over or undercharge Should control voltage range from (when engine running) 13.8-14.2 volts Without voltage regulator: Voltage could go to 18-24 volts causing electrical components to burn out

no
Why do the voltage battery light keep coming on after a new battery has been installed?
Ah, you have made one of the most common and easiest mistakes to make in automotive maintenance. Because the 'battery voltage' idiot light came on, you assumed that the battery was bad. Did you have an automotive electrical specialist test the electrical system on your car? Did you have the battery tested at a battery shop? Did you know that there are 3 primary parts to an automotive electrical system, and anyone of them can be responsible for the system operating below required voltage levels? Most modern automobiles generate electricity with a device called an alternator, which is driven by a belt from the crankshaft. The alternator generates Direct Current, at voltages up to 20 volts, in some cases. To keep the alternator from frying the battery, a Voltage Regulator is used to control the output of the alternator. This insures that the battery is only charged with a current of 18 volts, or less. Most modern alterators have the voltage regulator inside, but on older cars, the voltage regulator is mounted on the fender or the firewall, somewhere in the engine compartment. So, the alternator generates the electricity used to charge the battery, but the voltage regulator controls the output of the alternator. If the alternator is going bad, it may not be generating enough voltage to charge the battery. The battery is usually a 12 volt battery, and must see more than 12 volts to charge. Or, the alternator output might be reduced to an unusable level by the voltage regulator. Before you replace the entire electrical system, take the car to an automotive electrical specialist for testing. They can determine exactly which component is not working, and repair it. (Note: If the voltage regulator is bad, this DOES NOT mean that the entire alternator must be replaced! In almost all cases, the voltage regulator can be replaced by disassembling the alternator. If the specialist insists that the alternator must be replaced, I would recommend getting a second opinion, even though testing is often not free. Voltage regulators are fairly cheap, and can be replaced by a competent technician without too much difficulty. Alternators are expensive.)
Your headlights are dimming is it the alternator?
Check the alternator out put with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be 13.8-14.2 volts XXXXXXXXXXXXXXXXXXXX ANSWER XXXXXXXXXXXXXXXXX The voltage regulator is built into the alternator. In some cases it is cheaper to replace the alternator.
Will the alternator run the battery low?
If the alternator is not charging the battery, then it will eventually go dead If the voltage regulator (in the alternator) is defective it will eventually kill the battery Check the alternator with a voltmeter A fully charged battery (without engine running) should read approx. 12.8 volts With engine running should read 13.8-14.2 volts
