[John Mackie]

In 1951 Ford started using Luca 6 volt electrics.
Ford did make some 12 volt vehicles but very very rare untill the change to 12 volts in 1956.
If your starter and gene are Lucas they will have the model a date and 6 or 12 volts samped on the case.
The Lucas starter will interchange with the FOrd even though the drive is different.
The Lucas and the Ford 8BA gene were attatched to the mounting bracket with a band.the brackets are differenr becausec of the diamater of the case. you can use the single pulley 21A gene or one of the double pullry genies insrtead.
The Ford 2 brush genies can be modified to 12 V by using the case and field coils from an early falcon or late 62 or 63 truck . there is no need to change the armateur.
If the starter is 6V and wont crank on 6 volts make shure that the ends of the field case and end plate are clean and thaT THE END PLATE IS NOT DISTORTED due to over tightening the through bolts.Also check that the brush wires are making goodelectrical contact with the end plate.
