-[[Category:Charging System Modifications| ]]+Many different Datsun [[alternator]]s and alternators from other makes can easily be fitted to the Datsun 1200. 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.

Early A engine (1966-1973) has limited room for alternator. It is mounted low, under manifolds, on left side of engine. The larger 50A alternator will bolt to the bracket, but the alternator rubs against the lower radiator hose. It could be made to work, but is not recommended.

Many different Datsun alternators and alternators from other makes can easily be fitted to the Datsun 1200. 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.

[edit]

Overview

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?

Early A engine (1966-1973) has limited room for alternator. It is mounted low, under manifolds, on left side of engine. The larger 50A alternator will bolt to the bracket, but the alternator rubs against the lower radiator hose. It could be made to work, but is not recommended.

Stock Hitachi LT-135 35A

  • Weight: 8.4 pounds with pulley
  • Front flange (bolt ears): 13mm thick
  • Distance between engine-side mounting ears: 80mm
  • Distance between Adjustment bolt and mount bolt: 156mm
  • 10.5mm diameter mount holes
  • Diameter of body: 114mm (4.5")
  • Fan belt center: 29mm from front bolt face
  • Pulley diameter: 69mm
  • Adjustment bolt: Flange threaded for M8x1.25 bolt
[edit]

Electrical Connector

Datsun 1200 uses the typical 1970s Hitachi T-shaped connector:

  • F: Field
  • N: Neutral point

Other alternators use different connectors. Since the LT-135 uses spade connectors, wiring should be pretty simple.

[edit]

Hitachi LT-150

High amperage Hitachi LT looks like it will bolt right in place of stock LT-135 -- but on a B110 the alternator rubs against the lower radiator hose. It could be made to work, but is not recommended.

On later A12 it bolts right in place of the 35A unit, though a slightly larger fan belt may be needed.
