All "check" lights come on briefly when starting your engine. This is to make sure the light is working if soemthing does malfunction on your vehicle. If the light comes on while driving you may have broken or loose belts.
generally speaking, there are several LED lights on the battery charger, when the light is red, it meas the battery is being charged, when the light turn to green or yellow, it means the battery is full charged
I am going to assume you meant Three wires, Battery and Light Bulb. (punctuation and plurals are important) Hook the light to one post of the battery Hooked from the light to the item being tested (use the other light connection, not the one connected to the battery) connect the other end of the test item to the unused terminal on the battery. Light comes on means it conducts electricity No Light, it does not.
A light bulb and a battery simply being is not an experiment, so there is no variable at all.
Draw a battery and light bulb. Draw a line from the smaller connector on the battery to the bottom of the light bulb, this is positive on both. Draw a line from the bigger connector on the battery to the side of the light bulb,'this is the negative of both. Looked all over and can't seem to find this one.
The battery should be 4.5 v which is three 1.5 v cells in series. The power in watts depends on the size of the bulbs.
The battery light means your battery is low. You should go to a mechanics.
No
When our 93 grand prix battery light came on it meant that we needed a new battery. We tested the battery with a volt meter and the battery read 1 volt, it should be 12volts. Still wondering how to reset the battery light?
When the battery light is on. That means your charging system isn't working. You should have your system check. It will drain your battery.
Have the charging system checked. The light comes on when there is a charging system problem. it may be a battery, alternator or a battery problem.
the battery isn't charging as it should.
something is draining the battery. a new battery will last a couple days if just starting the car. even if your alternator is bad.
it's either your wiring or the wrong alternator or a bad battery !!
It could mean weak batteries. If it gets better on starting and rev the engine, it is the battery otherwise it could be your alternator.
The airbag light in the 2003 GMC ENVOY can be reset by disconnecting the battery for about 5 minutes. Then reconnect the battery, turn the key to on without starting the vehicle, and pump the gas pedal three times if the light is still on after reconnecting the battery.
disconnect the positive battery post and wait five minutes , then reconnect battery. The light should go out
Disconect battery for 5 minutes. Disconnect the battery for 5 minutes. Should reset engine light.
