Electrical craziness

[ericismyname]

Just last night after work i turned my car on and the Coolant, Battery light(idk what for sure it means), and the Brake light all stay on. occasionally when driving to school today all the lights turned off. buit they stayed on the whole way home from work last night. they are not all the way "on"(in brightness) but enough i can see them clearly. When i use the parking brake it lights up alot brighter. and when i accelerate my gauge cluster gets a brighter. Also when i have the clutch in, or im just coasting the gas light comes on. It did not do any of this before i installed my Air/Fuel Gauge. I have the airfuel gauge tapped into an ecu wire. but i know its tapped into the wrong wire becuase it stays on the farthest "lean" side. I am thinking about gettiny my battery and alternator checked to see if they are working properly. Any other ideas though?

First...... take out the mis-wired gauge!!!
From what I've read in these posts over the past year ... low battery voltage is the problem... for whatever reason. Typically the alternator has crapped out. It could also be the result of your wiring mess-up.
Let me know what you find!!
