I'm working on a 1999 Suburban and the battery keeps going dead. In two days it went from 12.5 volts to 11.6 volts. The battery is 1 year old and this started a few months back.

Are there any common parts or failures that cause this? I'll be diagnosing it this evening by connecting an amp meter between the battery cable to verify it has a significant drain (more than 50-100 mA), then pulling fuses one-by-one to find the circuit.

Thanks!
