Recently I've noticed the battery & brake wear light indicator come on and remain on until you remove the key from the ignition. Even when you are driving both lights are still on. Any suggestions? I've replaced all the fuses. Help!!!!

Whenever the battery light is on then the system isn't being charged. The most likely cause is the voltage regulator, and then the alternator is the next most common failure!
Have it tested as soon as possible.

In all cases that I have seen where the battery light is illuminated the alternator is faulty internally and needs to be replaced. The only way the light can come on is by passing current through the contact brushes in the voltage regulator.
