If it's a laptop, it's running off of the battery.
Otherwise, it has a very adaptive power supply... but you shouldn't run your computer in that condition (called a Brownout)
Sounds like it could be low voltage Battery charged? Alternator working?
The lights are computer controlled. The under hood computer can set codes and keep the lights from working.
Ask teacher for answers
signal lights not working.
The initial draw of electricity causes a fluctuation in voltage until all the internal capacitors are charged. After that the unit won't draw as much voltage and current.
It means that the voltage is going up as the alternator spins faster. 4 posibilities; 1 Your battery is dying and the alternator is working harder to charge it when you accelerate. The lights are comming up to full brightness. 2 You have a bad connection at the battery terminals or frame ground and the battery can't hold the voltage down. The lights are receiving too much voltage and are more likely to fail. 3 The voltage regulator on the alternator is failing and overcharging the battery. The lights are receiving too much voltage and are more likely to fail. 4 The battery needs water. The lights are receiving too much voltage and are more likely to fail.
The starter motor requires a great deal more of electrical current than do ordinary light bulbs. The lights working is not always an accurate measure of the battery condition.
The purpose of computer lights are to see inside your computer. If a part is broke, then you can turn on the lights and fix the broken computer parts.
Use a voltmeter. The normal choices in the US are 120 v and 240 v. If there is no voltmeter, use an ordinary cheap 60 watt lamp. If the lamp lights normally, the outlet has the voltage marked on the bulb. If it's too dim, the outlet has a lower voltage. If it flashes and dies, it's a higher voltage (I said use a cheap lamp).
The types of construction lights that are available are high voltage beam light and a low voltage beam light. The high voltage beam light shines a lot brighter.
Watts are calculated by multiplying the voltage by the amperage. To calculate the wattage you need both these numbers
wheel locks up and abs light come on because abs not working on that wheel lights go dim because alternator not working completely
