battery light and brake lights come on when at idle, go of when engine revs alternator and battery good brake fluid good any ideas?
 
alternator could be going bad there are 3 diodes in the alt. that works various parts of the electrical system and one of them could be going bad. when an alternator that i had in an oldsmobile went bad all my instrument lights came on so check that first then check your ground straps
