Its just el cheapo gage,,so it may not be very acurate,,mind you I had radio on so that uses bit of juice..
Theres also green yellow and red warning lights,,its interesting to watch how it works,,sometimes when driving it stays in red then goes green again,,the alternator must be charging when the motor is running,,so Im not sure why the red even comes on..
Maybe the car computer uses some power also..most important truck runs like a dream in any weather,,thats what counts..
