Colin,
I didn't actually disconnect the motor, I simply unbolted it and laid it on the floor then re-connected the direct to battery earth connection and tried operating it.
The battery and cables are all new but this does mean that on the positive side the starter button was still in circuit and on the earth side the battery isolator was also in circuit.
I've just tried measuring the voltage between the positive and earth connections to the starter but without the starter actually connected and this is 6.2 volts which is almost the same as across the battery so I don't think it's volt drop although I suppose the situation may be different under load.
John.
