 Dash lights This problem just happened on my way to work. When the rpms go past 1k the battery, handbrake, and the coolant lights go off. Only way they'll turn off is when the needle is under 1k. Anyone know what this is. Im sure its a common problem, a short or something?

Re: Dash lights it can possibly be your alternator it might be dying which is a common thing due to the fact where the alternator is located. If it is I have a good used alternator you can buy.

Re: Dash lights Try disconnecting the battery with the car running and see if it dies to verify whether its the alternator ?

Re: Dash lights Pull your alternator and have it tested and check your grounds. My car was doing the same thing. Usually the Christmas tree is the celebration of a dying alt.  The sensors are designed to measure the difference in voltage going to and from the sensors. And when the voltage on the way back drops below a set level, it turns the lights on. When your alternator is not working right, it will either not send out enough, or send out too much.. Which causes the lights to come one due to low voltage. All three at once is a good clue.  But what do I know, I just work on planes.

Re: Dash lights Ok so I changed the alt and the lights are gone. Now I'm having trouble with my radio and the lights on the rear view mirror. The stereo keeps turning on and and my lights don't want to turn on. WTF!!

Re: Dash lights Check your fuses including the large alt one.
