What is a B+ wire?
B+ voltage refers to the voltage found at the positive terminal of your battery. With the engine off, this is typically a bit over 12 volts positive, engine running it should be more like 14.4 volts.
When do you use the ACC battery wire?
The ACC wire offers power/electricity only when you insert car key into ignition switch and turn it to the left 2. Wire name: 12V battery (+) The 12V permanent battery wire will always offer power/electricity when the vehicle is turned on or off 3.
Where is the ground cable on an ACC-BPC?
Once you’ve found a power source that is Positive, simply wire the Red Cable on the ACC-BPC to that power source. One item that you may find useful when doing a fuse box install is a fuse tap. The black cable on the ACC-BPC is the Negative (ground) cable and should be connected somewhere on the body of the vehicle as the ground.
Why are there 3 pins on some batteries?
That third contact is connected to an internal thermistor, enabling the charger to measure the battery temperature. In mobile phones, some Li+ battery packs have 3 terminals.
What is the ground pin on a microcontroller?
With a microcontroller, the ground pin is the reference against which the inputs are ‘measured’ to determine whether they are high or low. Current Return: All the current that flows into a micro-controller has to flow back out again somewhere. You’re certainly aware that current flows into the +5V pin.

How is the ACC wire connected to the ignition switch?
The ACC wire offers power/electricity only when you insert car key into ignition switch and turn it to the left The ACC wire needs to be connected to car igniton 2. Wire name: 12V battery (+)
Where is the grounding point for a car battery?
That wire should be routed to a grounding point on the negative side of your vehicle’s electrical system—the negative side of the battery is a good choice. Also, make sure the grounding point is free of paint, rust, or plating, which can prevent a good ground connection.
