  1. Mtrob started following 2000 Silverado battery drain
  2. Mtrob
    My 2000 silverado 5.3 4wheel drive keeps running the battery down. With using the Power Probe tester plugged into OBD port then battery neg disconnected im showing a draw of 130mA. It should be below 40mA. The drain goes away when I unplug the horn relay. The horn is disconnected. So with that test it is after the relay between it and the horn. Is there anything else on that circuit?
