Hi guys,
My jaguar always lights up the battery warning but I have no ideas to find out the reasons.
Here's my situation:
If the car's temperature is cool, the battery light will burn if I use my air-condition while I just started the engine. But it won't lights when I use air-condition after I have driven for few meters or minutes later.

Second, if the car's temperature is normal it will light up when I restarted the engine. And I think it won't charge since the lights shows up.

I already changed battery and it's cable. I also replaced a new dynamo few days ago and it doesn't work. I still saw the light.
Hope you guys can let me know how to solve the situation like this.
Thanks
Mike

 

You say: I already changed battery and it's cable.

Which cable? The ground cable can cause problems, maybe more so than the positive.

 

Thank you for the reply,
I replaced my positive cable and the problem disapeard for few days.
But after those days, the same situation showed up.
Therefore, I will check my ground cable.
If the ground cable is fine, does anything else causes the problem?
Thanks
