there would either be a short to power in your switch / a short to power in your wiring somewhere between the battery and the bulb . somewhere in there electricity is constant and completely cuts out the selector switch. the lights turn off when you disconnect the battery because that is the only time that power is not applied to the bulbs.
Maybe you'd like to explain what you mean. I can't believe you actually want your headlights to remain on all the time - you'd flatten the battery.
sounds like a bad light switch.
Cars don't turn off completely, they run on battery power. The headlight switch needs to be turned off.
Sometimes an alternator with a weak diode(s)can test out fine, but can still trigger the light. I believe the problem is in your alternator. Good luck.
Turn the ignition key to the accessory position which is normally counterclockwise. Only the radio will be drawing power. If you have a good battery you could listen for a couple of hours without running the battery down. Any longer and the battery may go dead. Make sure that the headlights are off; these may still remain on when the key is in the accessory position. Headlights will drain the battery very quickly. It may also be advisable to run the engine for a few minutes every half-hour or so, to recharge the battery.
Ruin the battery.
Headlights are generally wired in parallel. This way, if one headlight is to burn out, the others remain lit.
The headlights require a vacuum to operate down. If there is no vacuum they remain in the up position. You may have a vacuum leak such as a disconnected or broken vacuum line. I have also seen the vacuum reservoir can rotted out and unable to hold a vacuum.
The life of the battery. You never have to change it.
No ~ but the battery VOLTAGE must remain the same.
you probably have a bad headlight switch.
You can bypass it by removing the three pin plug from the lock cylinder. This will only be successful if done while the engine is running. It will remain in "code accepted mode" with wires disconnected at this time and no new inputs! This proccess may or may not need to be repeated if battery power is lost.
I had this problem with my 1994 Buick LeSabre and it no longer happened when I installed a new battery. It's been at least 6 months now with no recurrence of the problem. Before the new battery, I noticed that if I waited about 5 minutes after turning off the car, I could get the lights to turn off. Seemed like something had to cool down.
Had this problem on a 1995 JCL, it was the DRL (daytime running lights) module. If you're lucky yours will cost $100, mine was $350. It was located to the left of the steering column and over a metal plate (white box) completely hidden from view. Do not buy Jeep, they are electrical problem prone and nightmares.
All lead acid batteries are always charged with the caps on. What this prevents is the acid accidentally boiling up an out of the cell and doing damage to surrounding equipment. When a car battery in a vehicle is charging when the engine is turning over, the caps remain on. This procedure should be no difference when the battery is on a plug in battery charger, the caps remain on. There are vent holes in the caps which allow any built up pressures to release.
It is usually caused by a bad alternator.
Yes they should , they stay on all the time , while the ignition is on all the best Fester
it's either low on oil or the sensor is bad. if you KNOW the oil level is full then the sensor has gone away on you.
It is possible that both bulbs are blown, but it is probably a fuse. Also check for a bad ground wire.
To reset an alarm for a 94 Corolla after changing the battery, place the key in the ignition and turn it slightly. Let it remain in that position for several minutes before starting the car.
There are a couple of things that can cause your middle stop lamp to remain on. The most common cause will be a loose or corroded ground wire.
Unlike older vehicles, today's vehicles have computers and other electrical components that require the battery to remain connected to the vehicle circuitry full time thus requiring a small but constant use of battery power. A battery maintainer will keep a battery charged and can be connected full time without overcharging. These are pocket size version of the automatic battery charger, but only have low current capabilities of 1 amp or less.
Everything that is plugged into the mains socket and switched on will use electricity even if it's a battery charger with no batteries in. So yes they do draw electrical power from the mains.
just bcuz you brought it new doesn't mean it can not be defective take it back to the seller and have it checked this problem happens very often because alternators are not new anymore they are remain parts
Most inverters will not be harmed by charging the battery [running the engine while the inverter is connected]. However, for safety [inverters are expensive] it is best that the Owner/User Manual be consulted to make sure that it is safe to charge the battery while the inverter is connected.
