 |
|
OK, I swear to god I didn't leave the lights on. Since I live on a hill I tried to compression start it without any luck. I took the battery to O'Reilly's who is charging now. There has been an occasional buzzing under the dash recently. Are they connected? What could draw the battery down overnight?
Thanks! |

While it's at O'Reilly's have them do a load test on your battery. They probably will anyways since they would love for you to buy a new battery from them. You don't say what year your car is but the buzzing could be your seat belt buzzer? And if was continuously buzzing that could drain your battery overnight with the cold conditions and a weak battery. Otherwise you could use a multimeter and read the resistance without your battery connected and see how much of a load your electrical system is drawing just sitting there without any lights on, radio, etc. If it is an excessive amount then the tricky part is finding what is drawing the load.

If there is any draw with it shut-off, than that is too much.
A quick check is with key off remove negative battery cable from battery, then touch it back and look for spark.
And while it is off, clean connections (otherwise gen/alt does not charge battery)

Has your commute changed lately? If you're daily driving is reduced, the battery may not have a chance to recharge the conventional way.
