Q: Battery drain.

asked by on December 20, 2016

I replaced my battery at autozone a couple of weeks ago, although I am not really sure why, but they did say that it may be weak. since replacing, I have had the battery light come on twice, but it went away. they replaced the battery today and said that it drained by 50% pretty quickly so they said there was a drain on the system, although never had a problem until just after replacing the battery. I did notice a very tiny wire in the battery compartment that goes nowhere and wonder if that got cut? but they said the wire was like that when they initially replaced the battery. going out of town tomorrow so would love a quick answer if possible.

thanks!!
