As of yet, nothing has broken, I'm just trying to figure out why they drop. Its normally around 700-800 on idle, and when I roll down my windows, they drop to 450-500. After I let go of the button they jump right back up however. Just curious to know if this is normal, or am I looking at a potential alternator problem? (limited knowledge here, please be kind)

Ditto. If you don't have a wire brush, just pour some coffee on the terminals, it'll eat away the corrosion if present. Another thing, ensure the terminals are tight, especially the ground.You may also want to try is hooking a voltage meter to the battery while the car is running to see how many volts are being generated. When it's not running, you'll see about 12 volts. When it is running, you should see about 14 volts (give or take). If you have much less than that, perhaps your alternator is on it's last leg...Originally posted by peterdonjuan View PostMy car use to do the same thing i checked to battery and it was corroded so i cleaned it with a wire brush and changed the cable terminals. thats what fixed it for me i would check to see if you battery is corroded.Comment
