B + - Abbreviation for the positive side of the power source.
BASE - One of three elements or terminals of a transistor, usually where an input signal is applied.
BATTERY - A device which converts chemical energy into electrical energy. A group of complete electrical cells assembled in one housing or case.
BATTERY ACID - A solution of sulfuric acid used as the electrolyte in automotive storage batteries.
BENDIX DRIVE - A starter drive system design used to engage the starter motor shaft with the gear teeth on the flywheel. Disengages automatically when the engine starts.
BIAS - Term used to indicate a certain voltage operating position or range.
BINARY - A number system using two digits - 0 and 1.
BLOCK DIAGRAM - A simplified schematic diagram made up of boxes labeled with the circuit functions.
BRUSH - A pad of electrically conductive material that bears on the commutator to provide an electrical circuit between rotating and stationary components. See also "commutator"

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
