Datsun 1200 was fitted with Mitsubishi or Hitachi alternator,.which were a lightweight (8.4 pound) 35 AMP alternator. These alternators will usually last 10-15 years or more than 100,000 miles before maintenance is required. The only normal maintenance is to replace the brushes when the dashboard alternator light starts flickering. The alternator uses an external Voltage regulator.

Early
Hitachi Alternator LT-135 (35 AMP model) was used on all Datsun 1200s up into the 1980s. Mitsubishi was the second source.
Interchange
Strict interchange: Alternator (35 AMP model) B110 1970-1973 B120 1971-1985 B210 1974 standard duty USA 510 1968-early 1971 USA 521 1969-early 1971 USA 620 1973-1979 USA
Loose interchange: Many kinds of alternators. See main article: Alternator Upgrades
Late
Japan-market Datsun 1200s from October 1981 came with a 35A alternator with integral regulator. It is a DIRECT BOLT-ON for the stock 1200 35A alternator, and requires a one-wire connection. You can unplug or discard any external voltage regulator. Also used by Australia N10 E13 and other Nissan.

Late model Datsun in Australia use a Bosch internally-regulated alternator.

Mounting
Also see Head Face - alternator mounting bosses
Early A-series engines (1966-1973) mount the alternator down low on the left side of the engine, under the intake manifold as shown in this photo:
1974-up engines mount it high on the right side of the engine:
For the A Engine Redesign, the alternator was moved to this right-side position to make more room for accessories such as Air conditioning pump or Smog pump.

Moving Bracket
Got a late-model A-series engine? Bolt the alternator to the left side down low for a cleaner look. No factory bracket bolt bosses here, but a simple adapter plate can be fabricated from a flat plate. Bolt to the block with the three outside holes, then bolt the alt. bracket to the two close holes. Size up a new fan belt and you are done.

Wiring
See: Alternator Wiring article.
Testing
The alternator should output 13.5v to 15v at 1200 RPM. A voltmeter is the only tool needed for testing.
The charge lamp on the instrument panel should come on before the engine starts, and go off while the engine is running. If the CHG light does not come on with the key (before the engine starts), then the alternator will not charge -- so replace a burned-out bulb right away.
If your charging system is not working correctly, see Alternator diagnoses

Regulator
B110 uses an external voltage regulator. It uses a connector with spade terminals, and so is different from B210 which uses round pins. It controls the alternator output to between 13.5-15.0 volts.
See main article: Voltage regulator
Upgrades
If you are running high-power headlights, off-road lighting systems, or high-power stereo gear, using a high output alternator is called for. Or, if you need to replace the 1200 alternator and have free or inexpensive access to different alternators, you might consider a swap. Lastly you might have a bad Voltage regulator, and by swapping to an internally-regulated alternator reliability increases since these use a solid-state (no moving parts) regulator.
