Datsun 1200 was fitted with a lightweight 35 AMP Hitachi alternator. These alternators will usually last 10-15 years or more than 100,000 miles. The only normal maintainence is to replace the brushes when the dashboard alternator light starts flickering. The alternator uses an external Voltage regulator.
The early A-series engines (1966-1973) mount the alternator down low on the left side of the engine, under the intake manifold. 1973-up engines mount it high on the right side of the engine.

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.
There are two major considerations in a swap:
- Physical swap. How does it bolt to the A12 engine?
- Electrical swap. How will the new alternator be connected to the wiring?
For more details, see Alternator Upgrades.
