I really feel like a idiot sometimes. I bought a Pioneer AVH-P5000DVD. I ordered a Stinger digital voltmeter to go along with my future electrical upgrade. The meter keeps craping out on me whenever I turn the car on or off. One time, it only illuminates the Stinger symbol, the next time it works fine. The next time, it only illuminates a few lights. Then, the next time a couple of the led lights stay on after turning the car off. If I disconnect it from the battery, it resets and works fine for a while. I think it's just a bad meter but I want to make sure I have it installed correctly before I send it back.
I have the red constant 12V wire connected directly to the battery, the ground is connected to the chassis and the blue 12v trigger wire is connected to the red ignition switch 12v wire on the back of the Pioneer.
