Upgrade Compatibility

The LR135 is a DIRECT BOLT-ON for the stock 1200 35A alternator, and requires a one-wire connection. You can unplug or discard any external voltage regulator.

It bolts on, and uses the same fan belt as the 35A older LT135 alternator. Just be sure to disconnect the external voltage regulator.

Wiring

The LR135 will fit B110, but has S+L wiring instead of F+N wiring. So one or two jumper wires are required.

• When replacing an FN-wired alternator (such as B110), see Alternator_Wiring#Late-model_Alternator

• When replacing 4-wire alternator (such as B10), see IR Alternator In Older Datsun

Dimensions

Dimensions are the same as the LT135 externally-regulated alternator.

Distance between lower mounting ears: 80mm
Distance between Adjustment bolt and mount bolt: 156mm
Fan belt center: 29mm from front bolt face
Pulley diameter: 69mm

Wiring

The LR135 has LS wiring like many modern Japanese alternators. The L-terminal goes to the CHG lamp, and the S-terminal goes to either IGN or straight to the battery.
