Elantra L4-1595cc 1.6L DOHC 16 Valve (1995)
Alternator: Testing and Inspection
Regulated Voltage Test
Ensure alternator drive belt is properly adjusted and battery is fully charged before performing the following procedures.
1. With ignition switch in Off position, disconnect battery ground cable and connect a digital voltmeter between alternator S terminal, Fig. 3, and
ground.
2. Disconnect alternator output wire from alternator B terminal, then connect a DC ammeter in series between the B terminal and disconnected output
wire. Connect positive lead of ammeter to B terminal. Connect negative lead to disconnected output wire.
3. Set engine tachometer and reconnect battery ground cable.
4. Place ignition switch in On position and note voltmeter. Reading should be battery voltage. If reading is 0, there is either an open circuit in wire
between alternator S terminal and battery positive terminal or a blown fusible link.

5. Start engine, keeping all accessories and lights off. Run engine at a constant 2500 RPM and read voltmeter when alternator output current drops to
10 amps or less, Fig. 6.
