The tail lamp fuse is out. This happend on my 94 q45
I obviously means that there is something wrong with the alternator or battery. When both lights are on 80 percent of the time its the alternator. Either your belt fell off or your alternator went bad.
either a fuse for dash or the light switch
If you mean all the warning lights come on at once this usually indacates the alternator is bad. It is either under or over charging (usually under) is a typical Toyota sign of an alternator going out.
Have your alternator checked out.
Possibly the alternator.
Your voltage regulator is shot. It is integrated in your alternator. You need to replace the alternator.
Im assuming these turn of after startup. When the alternator isn't running, these lights automatically come on. Your alternator doesn't start running until your car is running, because it is run by a belt from your engine. So, if your lights stay on after startup, either you have a snapped alternator belt or your alternator is buggered. We had our alternator belt snap the other day while we were driving down a hill, it was quite a scary experience as we didn't know what was going on and in automatics the breaks barely work without the alternater running.
Yes.
Either your battery is dead, or your alternator has failed.
There are several signs that an alternator is going bad. A few signs are dim lights, smell, warning lights, and a dead battery.
Check for poor ground connection either at the alternator or follow the negative cable coming from the battery.
mostly likely when you got the overcharging a fuse or relay was blown. need to locate and replace fuse most likely but possibly a relay.
