Ok here's the deal boys. I bought an Optima Yellow Top battery a long time ago. And there's a power draw that I didn't pay attention to for a while and now it's murdered my battery. I have to unplug it every night or it doesn't want to start the next morning. After driving for a while I'll have a full 12v (usually around 12.04, but example right now *after leaving it unplugged over night I'm down to 11.53v* So I know the battery itself isn't holding the charge as much anymore. And I have located two fuses that are pulling power.
The 10amp fuse for the "dome" which I believe controls the cigarette lighter *which hasn't worked since I've owned the car*, the clock and the dome light. It is pulling 650 milliamps. Secondly, the 20amp fuse for the radio is pulling 175 milliamps I believe. Now I know the radio one isn't an inordinate amount, but if I leave the car hooked up over night that one item is enough to make it not want to start. I have removed the Dome fuse because, until i can figure this out, I'm ok without those items working. What the eff do you guys make of this? Discuss, diagnose, help fix. Go. -------------------- ![]() |

FULL charge on an optima battery is the 12.4-12.6 range. Lower than that and you risk not having enough voltage to sustain starting the car. I would highly recommend trickle charging the battery (2a or less charge) overnight to really top it off.
Unplug both items/fuses (like completely remove stereo if you can) and leave overnight, check voltage in AM. If OK, plug stereo back in as it will usually pull some amperage when "off" due to memory stuff. I'm betting it's on the dome light fuse/circuit. Check if the ash tray light is on that circuit, it could be sticking on for some reason. The cigarette lighter is a very potential cause due to you saying it's never worked......just hollers potential short in the wiring. -------------------- |
