Trev Aus covered this topic for datsuns

a genny to alternator conversion

what I would like does someone have the fitting instructions if the alternator has an external regulator
so we can do away with the dynamo control box


The polarity of the alternator can not be changed, so if the alternator you got does not conform to your car, you must change your cars set up . The existing car polarity can be checked by looking at the battery to determine which of the battery leads go to ground.

The ACR series alternators are self contained units; their outputs are as follows: 15ACR-20 AMPS; 16ACR-34 AMPS; 17ACR-43 AMPS; 18ACR & 20ACR-45 AMPS; 22ACR & 25ACR-55 AMPS.

Alternators come in either polarity, however most later ones are negative ground, in which case the alternator will have a “+” sign next to one of its large output terminals.

VEHICLE POLARITY CHANGE (IF NECESSARY)

ALTERNATOR FITTING
Bolt the unit on in place of the generator, noting that you have removed two wires from the generator ( a thick one and a thin one ). Push the thick wire with the large connector on either of the large spade connectors ( usually marked “S” or “+” ) on the alternator. The small wire goes on the terminal marked “IND” or “WL” .



DYNAMO CONTROL - BOX REMOVAL

On the solenoid this extra cable should be connected to the same terminal as the main battery cable ( not the starter motor feed ). Use only thick heavy wire (e.g. size 65). This will make the system more efficient by reducing the voltage drop, specially when the alternator is putting out a lot of AMPS. If required, a radio interference suppresser, 1UF capacitor, can be connected between the “S” or “+” terminals to ground.
