Re: Battery keeps draining on me.....help!
An excellent troubleshooting tool is a test light, of any kind, whether it be a "real" test light or a back-up socket with a bulb.
Unhook the ground cable from the battery and hook the battery to the test light and the cable to the other test light lead. The brighter it glows, the more current being drawn.
Modern radios have "keep alive" memory and a clock, so maybe 10-20 milliamperes will be drawn. One doesn't want more than 50 milliamps with everything else off.
Back to the test light, pull fuses and the like till it barely glows, ie, radio. You might even disconnect the red wire from the alternator to make sure its not discharging the battery.
