| - | RHD Datsun 1200 was fitted with Mitsubishi or Hitachi alternator. North American models were equipped with a lightweight (8.4 pound) 35 AMP Hitachi alternator. These alternators will usually last 10-15 years or more than 100,000 miles before maintainence is required. The only normal maintainence is to replace the brushes when the [[Wiring#How_the_Alternator_Dash_Light_Works|dashboard alternator light]] starts flickering.

| - | = Wiring = | + | Loose interchange: Many kinds of alternators can be used with some mods (different length fan belt or mounting arm). May require a wiring modification. |
| - | See: [[Wiring#Alternator_.26_Regulator|Wiring]] article. | + | |
| - | = Testing = | + | = Late = |
| - | The alternator has four terminals: | + | Datsun 1200 from 1974 (with mid-distributor A12) came with various alternators. |
| - | * A - alternator connects to Battery cable + 12V via large white/red wire. | + | |
| - | * E - earth/ground. Connected to case of alternator, hence though bracket to the engine. Engine is grounded by black cable (part of the two-cable negative battery cable) | + | |
| - | * F - the Field. This needs 12V to get the alternator working. The [[Voltage regulator]] turns this on/off (12V) rapidly to achieve an average of 13.5-15.0 volts | + | |
| - | * N - Nuetral point. This is connected to the dash Lamp. This is optional, the alternator will function with this disconnected. | + | |
| + | == 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. | ||
| - | Test Procedures | + | * Nissan, Mazda, Subaru |
| - | * With engine off, check voltage at battery terminals. If it is less than 12.0 volts, stop. Charge the battery before continuing. A low battery can prevent a good alternator from putting out correct voltage. | + | * 1981-1989 JPN Sunny Truck 1200 |
| - | * With engine running at 1100 rpm, measure Voltage across battery cable. If it reads between 13.5-15.0 volts, everything is fine (or over 12.5 volts headlights on main beams) | + | * AUS Nissan Pulsar N10 |
| - | * Measure Ohms between F & E terminals. It should be approxmiately 5 ohms (with ohmmeter on lowest range). If higher or lower, remove alternator and inspect. | + | * AUS Nissan Patrol (with vacuum pump) |
| - | * Perform Regulator Bypass Test | + | * 1978-1979 USA Datsun 620 pickup |
| - | *# Be sure to test at A & E terminals, to bypass external wiring problems | + | * 1980 USA Datsun 720 pickup |
| - | *# Disconnect T-shaped connector (F+N) at alternator, to bypass the regulator wiring | + | |

| - | * Should be around 4.4 ohms (with ohmmeter on lowest range) | + | |
| - | ** No continuity means the winding is broken or detached | + | |
| - | ** Lower ohms may indicate a short, perhaps from bad insulation | + | |
| - | **: Neither condition is easily fixable. Replace it. | + | |
| - | Also check for isolation: | + | {{Album!|26024}} |
| - | * There should be no continuity (even using 1M-ohm scale) between either ring and the rotor metal or shaft. | + | |
| - | *: If there is, it is shorted. Replace it. | + | |

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.

[edit]
Early
Hitachi Alternator LT-135 (35 AMP model) was used on all Datsun 1200s up into the 1980s. Mitsubishi was the second source.

Interchange
Main: Alternator Upgrades
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.
[edit]
Late
Datsun 1200 from 1974 (with mid-distributor A12) came with various alternators.
[edit]
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.

Mounting
Datsun 1200 mounted the alternator on the left or right side.
Main: Alternator mounting
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
Main: Alternator Wiring
[edit]
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.
Main: Voltage regulator
[edit]
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.
