Technical Car dies with no power while driving!

[ycming]

Hey Peeps,

Just got home, the rev on the car been hunting all day. And tonight when i went for a drive, head lights on. After 10 mins of driving all the light gradually got dimmer and dimmer. Then engine management light then the car died with no pwoer can;t even restart it.

manage to get it home with a booster pack every 2 miles or so.

I have just cleaned the 3 earths again. Before this happened I have used general purpose grease on them, and brother said that could cause a problem.

So What could cause this? dodgy afternator or battery?

thanks

Also when all the light became dimmer, when the indicator is switched on, the rev guage just dropped, but the actual rev not drop( could tell by the tone of the engine).

Thanks

The battery output, without the car on 10v.

With the car on just under 10v ???

IS it safe to assume is a dodgy battery ?

Thanks

More likely dodgy alternator.

Does the ignition light come on when the ignition is in pos 1?

Should add, Got 2 battery both seems dead. one read 0v even when the charger is on it. One read 10v, even when the charger is on it.

The one that was on when i was driving is the one that gave 0v. No ignition light after it died.

The battery with 10v, yup got the iginition light/management light but not enough juice to spark it on!

Right right, is it good to say both battery is fooked?

I will need a battery regardless of the state of the alternator.
Then check when the car is on, it gives 13.8v or above?

Battery will have taken a hammering, but might well come back when charged.

Just to complete the information. When i put the battery charger on the battery with 10v, it seems to boil over and the fluid seems to leak out...

Could it be a dodgy battery charger?

Naw, the battery is fooked.

I also checked the reading of the battery charger, it is only giving 10v ???? But brother said something about pulse charging so is it ok?

Sorry for the Friday night bombandment!

When i started the car using the booster pack with the fooked battery, should it still give a reading of 13.8v ???

If it doesn't then does that mean is the alternator?

Thanks
Ming

More to the dilema, i stuck the booster on the battery by itself (the 10v one) for 5 mins. Now it reads 12.5v ?? which is normal....

Lost!

Slow down.

The battery will have taken a beating. It will actually recover itself even off the charger, the lead and acid make electricity.

It might get its volts back, but the amps are another matter.

The alternator should always give around 13.8 volts with th engine running.

If your battery has been boiled it is possible that the alternator is running far higher than 13.8.

Its been boiled over using the charger not when it is in the car.

How do you check the output of an alternator? Through the battery ?

Would it be possible that the battery hold 0 charge and meaning the power from the alternator is not getting to the car at all ? (I was using the 0v battery when the car died)

I think tomorrow, i will start it with the battery giving the 12.5 v and hope with the engine running it will give the expected 13.8!

Thanks

Right New alternatore fitted, but still get a reading just below 12v when the car is car ?

any idea peeps?

thanks
Ming

 

[ycming]

I have just swapped the battery from my working cinq, and now ti gives 12.38, but yet still not the expected 13.8 ...

So save to say that the old battery is dead?

Really lost now..

Thanks
Ming

 

[ycming]

The battery seems, fine i swapped it to the other cinq, and it is giving a value of 14.14 (that's not too high is it?).

Not sure if there is anything i can do, as the alternator is brand new?

thanks
Ming

Trip to Rallycinq's place answered my questions .

The battery light wire is not working, so it is not charging the battery on start up unless you give it rev.

So reved the car, check the voltage it gives 14v which is rather nice!

Really happy now .

Thanks D
