Does An Alternator Have A Ground Wire. 1-Wire alternators require only 1-wire to operate. The terminal is slid over the threaded post of a bolt and then secured by tightening a nut onto the terminal.
To help you avoid this there is an alternator ground cable that is designed to take any excess electricity from your cars motor and carry it away safely. Simply run one wire from the alternator battery terminal to the positive terminal of the battery or to the starter solenoid main lug which is connected to the positive battery post. An alternator typically has two wires - a main connection usually labelled B which delivers power to the car and charges the battery and an IND wire which feeds the internal exciter coils of the alternator.
You can add a wire from the chassis of the car to the engine block.
If you were to ground to the chassis and a smaller ground to the engine block it would not be so. A battery that refuses to take a charge is one sign of a bad ground. The sense wire is part of the charging circuitry. Make sure that the battery is fully charged.
