Engine wont crank!! Austin Ruby

Paul t, Have you tried a test bulb between the starter cable (where it connects to the starter motor) and earth it should light up when the ignition is switched on. Likewise connect you test bulb between a starter motor securing bolt and a battery terminal the terminal that will complete a circuit. (I can't say which one because I don't know what polarity your car is wired.) If they both light up it shows power is getting to the starter and you have an earth. Thus you need to look at the starter. If only the test lamp comes on when connected to the starter cable you fault lies with the Earth. If it only comes on when testing the earth (starter motor retaining bolt) then you have a problem with the power supply. Should it be that power is getting to the starter but no go then have a look at the switch on the top it maybe that the contact needs cleaning.
