im looking at a 2004 S10 extreme blazer for a friend, and the battery is going dead on it all the time. sears checked her battery and its ok. i had an ammeter on it all morning in the garage and when the vehicle goes to "sleep" i read 15 milliamps. what is the limit for this truck? i work on bmw's and we wllow 30 milliamps max after sleep mode is assumed.
also, anybody here know any common causes for draw on this truck? i heard somebody say the radios are prone to problems, and my friend did say that if she turns off the radio before shutting off the truck and locking it, the battery will not drain
