What a bad voltage regulator?
If you have a bad regulator, it may cause many components such as the fuel pump, ignition system, or other parts which require a minimum amount of voltage to not function correctly. You may experience the engine sputtering, a rough idle, or simply a lack of acceleration when you need it.
How much does it cost to replace an alternator voltage regulator?
A new alternator voltage regulator will cost you anywhere from $40 to $140 for parts, heavily dependent on the make/model of vehicle and whether using OEM or aftermarket parts. The cost of parts doesn’t sound so bad, but since most voltage regulators are housed inside the alternator, expect to pay around $140 to $240 in labor.
Where is the voltage regulator on a car?
The location depends on the make and model of the car. It will be either inside or next to the alternator housing. Ford is one brand that mounts it next to the alternator. Those mounted adjacent to the alternator need extra support, which is provided in the form of a harness.
When do you know you have a bad voltage regulator?
Once the car is running, the voltage should measure around 2 volts higher in most vehicles. If the output voltage is measuring at 16 volts or more, it’s very likely you have a faulty voltage regulator.
Can a bad voltage regulator cause a car to burn out?
If the output voltage is measuring at 16 volts or more, it’s very likely you have a faulty voltage regulator. Too high of a voltage can actually cause damage to various electrical components. Most commonly, the bulbs in your headlights or taillights will prematurely burn out.
When do I need to replace my stator on my ATV?
If your reading is not what it should be according to your service manual, then your stator should be replaced. This test makes sure that the stator isn’t shorting out to the ground. Your meter should read “OL” or open line. If the multimeter is picking up a reading, it means your stator needs to be replaced.
Can a multimeter be used to test a stator?
Some people opt to replace the stator without checking, but testing a stator is easier than replacing it as long as you have a multimeter. You can get a multimeter for $10-40 on Amazon, so you might as well just have one around for when you need it. In order to test your stator, you only need two things, neither of which is expensive.
How can I tell if my stator is bad?
The only way to know if it’s your stator is to test the stator itself. Luckily, testing is simple. Even those who aren’t mechanically inclined can test their stator by referring to their service manual and following the steps outlined above. So if you aren’t sure, do the test.
How to replace an alternator on a Briggs and Stratton mower?
This video covers the steps I took to replace the ALTERNATOR on my 18.5HP Briggs & Stratton Engine for my Craftsman Riding Mower. This included replacing the VOLTAGE REGULATOR and removing the FLY WHEEL. I include a lot of detail footage showing each step involved in getting to…and removing…the Fly Wheel in order to access the Alternator.
