How do I know if my voltage regulator is working?
Connect the positive lead of the multimeter to the output terminal of the regulator and the negative lead to the ground terminal. Turn on the power source and read the output voltage on the display; it should match the rated output voltage of the regulator (e.g., 5V, 12V).
What does a voltage regulator do when it goes bad?
You may be able to drive with a bad voltage regulator—but not for long. If the regulator is causing low charging system output, the battery will eventually become discharged and the vehicle will no longer run.
What happens when alternator voltage regulator fails?
A bad voltage regulator can lead to the alternator undercharging or overcharging the car’s battery. Undercharging can result in a discharged (dead) battery, whereas overcharging can cause internal battery damage. If neglected the bad regulator can permanently damage the battery.
Can a voltage regulator cause no start?
Best Answer. No it shouldn’t.
Will a bad voltage regulator drain a battery?
Yes. It can allow the battery to be discharged to the point the car won’t start, which is very hard on the battery, and it can allow the alternator to overcharge the battery to the point it’s ruined as well. The voltage regulator is seldom a separate part these days.
Can you replace a voltage regulator without replacing the alternator?
In most cases yes and is a fairly easy job. Some can be done without removing the alternator.
Can an alternator work with a bad voltage regulator?
A bad voltage regulator can lead to the alternator undercharging or overcharging the car’s battery. Undercharging can result in a discharged (dead) battery, whereas overcharging can cause internal battery damage. If neglected the bad regulator can permanently damage the battery.
Where is the voltage regulator located?
Regulator is either attached to the alternator. Or inside of it in older cars with carburetors. It could be found on the firewall. Some newer cars don’t have a voltage regulator.
How do I know if my external voltage regulator is bad?
Signs of a bad voltage regulator in a vehicle include dimming or pulsing lights or a dead battery. If you have electrical equipment that won’t turn on, that could also indicate a bad voltage regulator—the regulator could either be letting no power through or letting through too much and damaging the other components.
Can you replace just the voltage regulator?
It is possible to replace only the voltage regulator on some vehicles – usually by disassembling the alternator to gain access – but because the other alternator components can wear out over time also, the alternator is commonly replaced.
