startee the car today, battery light immediately came on and is staying on.
i do not have the f82 fuse (later 2004 x type 3.0)
anyone know how to troubleshoot?

 

I have problems with the battery ight in the past on mine. So far I have been lucky.Disconnect and thoroughly clean and reseat the battery cables first to see if that cures the problem.
Second, if that didn't do the trick you will need a multi-meter and take a voltage measurement of the battery post to ground and then the battery cable to ground while they connected and the engine running.
There should be none to an extremely low difference between the post and cable. The voltage should be somewhere in the neighborhood of 13.5 or more volts at idle.


Check those and get back to us and wew can move on from there.

 

Make sure you are turning on the headlights and ac to read voltage. If the voltage doesn't rise and drop with each additional electrical component, the regulator is shot. Mine read good at idle and when the headlights came on it would immediately drop to 11v and in a few days, stranded. With components off it would drive "good".

 

Try checking the battery connectors they corrode and cause the light to turn on also make sure its secured with the clamp, its always a chance the actual battery might be bad or the alternator.

 

today the light is not on so im hoping the damp weather caused a glitch.
attached a multimeter and all seems ok.
thanks all for the input.
battery is about 2 months old
