I am having this problem with my corolla....
Yesterday I was driving to the library, and then the charge light came on. Understandably I was quite concerned about this, so after I went to the library, I went around to my friends house and we checked the voltages...
It seems that it is chargin correctly, as with the car off, the battery reads 13.5V, and with the car running, the battery reads about 14.5V.
In adition to the charge light not working, the oil light does not work,a and the fuel and temperature guages read low!
How can I fix this horrible problem!
