Well, since there's no smoke or fire, I doubt it's shorting out, so I'd have to say that's a bad battery (if you're measuring at the battery terminals right on the battery itself)
It's not unusual for a battery to have full voltage in a no-load situation and drop to almost nothing under load.
Just to be safe though, I'd disconnect one of the battery wires, and measure the resistance when the ignition is on. It might be low, but it shouldn't be 0.
While the battery is disconnected, hook a 12V light (maybe a spare turn light or headlight or something) and see if the battery still drops to nothing.
If it does, then it's definitely the battery.
When a battery becomes like this, they usually cannot be charged and need to be replaced.
Take your battery with you when you get a replacement. This ensures that you get the right one, plus most places give a recycling discount for returned batteries (IE - new battery cheaper).

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.
Visual Inspection Chart Mechanical Electrical
  • Battery case, posts, hold-down clamp, cables and connections
  • Generator drive (serpentine) belt for condition and tension to make sure there is no slip between the belt and the pulley. For additional information, refer to Section 303-05 .
  • Battery charge
  • Generator pulley

  1. Check the operation of the charging system warning indicator lamp (instrument cluster). Normal operation is as follows:
    • With the ignition switch OFF, the charging system warning indicator should be OFF.
    • With the ignition switch in RUN and the engine off, the charging system warning indicator light should be on.
    • With the engine running, the charging system warning indicator light should be off.
  1. Verify the battery condition. Refer to Section 414-01 .

    Your whole problem is the alternator is not charging , a couple tests with a volt meter would tell you !

Wont turn over


#1 battery condition , wire connections , 12 volts to the ignition switch , all dash lights coming on ? if so then make sure you are getting power to the solenoid switch ck with text light , ck power 12 volts again at the battery side of the starter with test light or voltage test .I also think that power goes through the alternator to power the starter this is in older trucks but ck sounds like you are not getting power but must be more specific on the issues ,hope this help,

Mondeo elproblem


May be but I doubt it. The alternator is not putting enough power to keep the light out. IT works like this battery power (12 volts) flows through the light to the alternator and puts it on when the alternator starts to charge the extra voltage from the alternator (14.5 volts) flows back through the light and as the 2 volts difference is not enough to make the light work it goes out . IF you are measuring 12 volts at the battery and 12 volts at the alternator then then the alternator is not charging. What you should have is 12 volts at the battery and as you rev up the engine the voltage should increase at the battery up to 15 volts maximum at around 2000 RPM

ALTERNATOR/BATTERY PROBLEM


I would look for a large fuse or fuseable link between the alternator and the battery.

When my '95 Triumph Thunderbird gets warm, the neutral light will not come on when the bike is put in Neutral which also kills the starter. The problen rights itself if the engine is allowed to cool....


Sounds to me like the bike is not recharging thebattery as it runs, and when you turn of the ignition the battery regains about 30%of its charge which allows you to run again, connect a multi meter to the battery with the ignition off, you should have 12 to 14 volts preset, now run the bike the voltage should rise to aprox 12-16 volts DC any readin lower than 12 volts could indicate a charging problem, hope this helps

Whe i turn key the ignition lights come on but when i turn it again to start it the engin dose not turn over you get no sound from under the bonnet


It sounds like your battery is dead. The lights don't take much power to come on, but as soon as you turn the key to start the engine the starter doesn't have enough power to turn over. Take your battery to a Autozone or similar and have the battery load tested and tested for bad cells. You can also check the voltage level of the battery although this isn't a clear indicator of a bad battery unless it is below 12 volts. If it shows around 12 volts, have the battery tested. If the battery checks out, have your starter tested.

My 06 Coblat LT wont start unless I jump it almost every time. Is this the alternator?


If it starts and stays running it's most likely the battery. However,With a voltmeter while the car is running measure the voltage at the battery terminals. If the voltage is about 13.5 volts to 14.5 and there is no battery light indicator on in your instrument panel, your alternator is most likely good and trying to charge the battery, If the battery light is on and you have lower than 13.0 volts at the battery most likely the alternator needs to be replaced. Turn the ignition off and measure the voltage again if it's 12 volts or less try charging the battery with a trickle charger (2 amps setting) for about 12 hours.if the problem persists replace the battery.
