When headlights are turned off parking lights remain on running down the battery What is wrong?
sounds like a bad light switch.
Which component of the ignition system would most likely be the culprit for battery drain?
Dead cell in the battery. A light is on drawing power from the battery. You may also have a relay that is stuck.
Would the ignition switch control the dash lights?
It sends a power to the starter relay/solenoid to engauge the starter. Know that the ignition switch is not what you put the key in and turn. That is the lock assembly. The ignition switch is located lower down on the steering column.
My car won't start and there's no clicking noise?
A couple of things to troubleshoot here first: 1. Do the car's lights work? Not the interior light, the headlights. If the headlights don't work or they go completely dim when you turn the key, your battery is dead.
What light indicators come on when ignition switch is turned on?
the radiator was replaced and the fluids are still evaporating or leaking out somehow. what other options could be wrong with the car overheating?
When you turned the ignition key a click sound acured and then the ignition lights not on only the key light?
You have a flat battery.
Why would the battery light stay on after the ignition is turned off on a 1986 Nissan pickup?
The voltage reg is sticking and will run down the battery.

Had trouble starting car put key in turned twice but nothing lights lit up?
Check the battery. Turn headlights on - they will come on with or without the key if it has power from the battery. If lights do not come on, the battery is dead (try jump-starting) or there is a bad connection (loose cable), or a short in the electrical system. If headlights come on, but dashboard lights do not light up - check the ignition (cylinder / switch)
Why does the battery warning light come on when the ignition is switched off?
I had this problem on my disco 1. Turned out to be the alternator, which was replaced and the problem was fixed.
Please explain the charging circuit in automobile. 1. How does the charging light comes on when ignition switch is turned on 2. How charging light comes on when alternator is not or less charging?
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
You want to try to uplug your battery to take off your check engine light does the car have to stay on?
Never unhook the battery with the ignition turned on. There is always a little voltage spike that occurs when disconnecting or reconnecting the battery. If the ignition is on the computer will be powered up and that spike could "fry" the computer.
Why do the headlights on a 1986 celica gts come on and pop up by themselves when the ignition switch is turned off but will not work at all when the light switch is turned on or off?
Ever watched a movie called christine? Nah, check your wiring harness for the headlights and look for a bare spot(s) with wire showing...could be grounding
Why No battery light on when ignition turn on?
bulb no good.
Why do the dash radio and clock light dim when the head lights are turned on?
The headlights place a larger load on the battery and cause the voltage to drop enough to dim other devices slightly.
If you were traveling at the speed of light in a car what would happen if you turned on the headlights?
Nothing
How do you troubleshoot a 1983 Dodge ignition?
Battery first. Will it start with a jump? Battery ok, then use a test light & see if you have current in the hot wire to solenoid when key turned. If you do, it's the starter. If not maybe the switch but start there.
