Current revision

Datsun 1200 was fitted with a 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 dash 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 USA standard duty
 510 1968-early 1971 USA
 521 1969-early 1971 USA
 620 1973-1979 USA

Loose interchange: Many kinds of alternators can be used with some mods (different length fan belt or mounting arm). May require a wiring modification.

Late

Datsun 1200 from 1974 (with mid-distributor A12) came with various alternators.

Hitachi LR135

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 (modified wiring). You can unplug or discard any external voltage regulator. Also used by Australia N10 E13 and other Nissan.

Lucas 15AC

Australian assembled 120Y have a Lucas alternator. Lucas 15-A.C.

Lucas AS123

Big-flange alternators were used in South Africa on the B140.

Bosch

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

Mounting

Datsun 1200 mounted the alternator on the left or right side.

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:

Wiring

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.

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.

Rebuild

A rebuilt alternator should have the following features:

* Bearing replacement
* brush replacement
* Slip ring lathe processing
* Cleaning
* painting
* metal parts plating
* new bolts
* new pulley
* test

The diode rectifier is not usually replaced, as it can last 50 years or more. Yes, they go bad, but there is no determinative age limit.
