2002 x type , battery light will come on once in a while, then it will
not show up next time i re start the engine.
checked battery voltage its 14.5 V with the engine off.
with New battery
Could it be the sensors?
That’s too high. Check the voltage with the engine running also, could be the alternator.
Fully charged battery should be 12.8v.
I know this is an old post. I had this issue on my 2004 X-type. It would randomly have the battery light come on. I began to notice however that I could pull over, turn the key off, remove the key, wait about 5 seconds and start the car, battery light out. Over a period of several weeks this would happen, every time a stop, remove key and restart turned the light out. I then began checking grounds and found one each on either side near the wheel wells. I removed, sanded the areas and replaced the grounds. Problem has never returned. I have the original alternator at 145K.
