| - | The Hitachi LR series of internally-regulated [[Alternator]] was first fitted to North American B210 for the 1978 [[Model year]]. It weighs about 2-1/2 pounds more than a stock Datsun 1200 35A model and about 1 pound more than an externally regulated 50A Hitachi. The LR160 60 amp model is physically identical, and was first used around 1983. | + | The Hitachi LR series of internally-regulated [[alternator]] was first fitted to North American Datsuns for the 1978 [[Model year]] and used in Australia in the 1980s. |

The [[620]] came with the LR-135 (35 AMP) which is same size as the Datsun 1200 LT-135. The B210 came with 50 AMP LR-150, it weighs about 2-1/2 pounds more than a stock Datsun 1200 35A model and about 1 pound more than an externally regulated 50A Hitachi. Also available in 60 amp model LR160 which is physically identical to the LR150. |

| - | == Automatic Choke == | + | |
| - | NOTE: If your Datsun was factory-equipped with [[Automatic Choke]], a second jumper is needed. See above. | + | |
| - | + | ||
| - | Alternate method of wiring the choke: With LR alternator: On the carburetor, unplug the electric choke. Make a new jumper wire from the choke to the ballast resistor (12V side). The downside of this is the choke starts warming as soon as KEY is ON, whether the engine starts or not. If you have trouble starting the engine, in cold weather you may never get it started, because the choke begins to open. | + | |
| - | + | ||
| - | + | ||
| - | === Original Wiring === | + | |
| - | The wiring harness for Datsun 1200 auto choke with LT-series alternator, for example, the 1973 1200 USA, the choke relay is connected to Ground. See [[Alternator_Wiring#Automatic_Choke_Relay]] | + | |
| - | <br>http://datsun1200.com/uploads/thumbs/14977.jpg 1200 relay, normally open. Alternator output will close the relay, activating the choke heater. | + | |
| - | + | ||
| - | The wiring harness for B310 with LR-series alternator, the choke relay is connected to IGN | + | |
| - | <br>[http://datsun1200.com/modules/myalbum/photo.php?lid=24362 http://datsun1200.com/uploads/thumbs/24362.jpg] B310 relay - normally closed. IGN switch will activate the relay, deactivating choke heater. Then alternator output will de-activate the relay, causing the choke heater to power up. | + | |
| - | + | ||
| - | The [[Choke Relay]] is wired oppositely different on LT-series and LR-series applications. However, since both are triggered by the Lamp/Nuetral wire, either alternator will work with either wiring harness/relay combination (old harness/old relay OR new harness/new relay). | + | |
| - | + | ||
| - | == Troubleshooting == | + | |
| - | 1. Check the Voltage at the alternator. Between the BAT terminal and the E terminal (earth/ground) there should be the same V as at the battery. If not, you got a wiring problem. | + | |
| - | + | ||
| - | 2. The S terminal should be 12V hot when key is turned to IGN | + | |
| - | + | ||
| - | NOTE: on the B310 with this, S is hot all the time | + | |
| - | either way will work | + | |
| - | + | ||
| - | 3. The L terminal (Lamp) should be: | + | |
| - | * 0V when key is turned OFF | + | |
| - | * 12V (more or less) when key is turnd ON | + | |
| - | + | ||
| - | Because the L terminal is the exciter, if your CHG lamp is burned out, the Hitachi LR won't charge. | + | |
| - | + | ||
| - | [http://i297.photobucket.com/albums/mm219/ddgonzal/sightings/forum/EL-19.jpg http://i297.photobucket.com/albums/mm219/ddgonzal/sightings/forum/th_EL-19.jpg] | + | |
| - | + | ||
| - | == Engine Won't Shut Off == | + | |
| - | If wired incorrectly, the engine will keep running when you turn the key off. | + | |
| - | + | ||
| - | == Regulator Still Plugged In == | + | |
| - | The FN wiring is different from LS wiring. So if you leave the external regulator still plugged in, the wires are incorrect. | + | |
| - | + | ||
| - | It won't cause overcharging, since the LR is internally regulated. | + | |

Current revision
The Hitachi LR series of internally-regulated alternator was first fitted to North American Datsuns for the 1978 Model year and used in Australia in the 1980s.

[edit]
Overview
The LR internally-regulated alternators came on newer A-series engines, from 1978 for Nissan North America, and from the 1980s for Australia. The 620 came with the LR-135 (35 AMP) which is same size as the Datsun 1200 LT-135. The B210 came with 50 AMP LR-150, it weighs about 2-1/2 pounds more than a stock Datsun 1200 35A model and about 1 pound more than an externally regulated 50A Hitachi. Also available in 60 amp model LR160 which is physically identical to the LR150.

Only a simple wiring change is required when replacing Datsun externally-regulated alternators.
