The reading of 1 would be infinity such as more than my digital meter can measure. I tested the right and left headlights and each of them read 1 when on. I know this is the circuit that was killing the battery. I have owned this car a year. I would leave the negative cable off of the battery when not working on the car. The radio did not work and I replaced it. I assumed the amps were staying on and killing the battery. Left the cables hooked up on the battery and it was dead in 2 days. I pulled every fuse and checked the amperage and circuit #2 was the power hog. When I pulled this fuse the car will crank no matter how long it sits. The battery is not draining with this fuse out.
