| To BY/C. from EFC. X4165- EFC2/T3.9.23. X.3014a - RE LARGE LUCAS DYNAMO FOR PATIALA X4165- This dynamo is now tested and ready awaiting your instructions. Some of the old colours are on the terminals - field, green, and control yellow - but we have attached labels to the terminals indicating these and their respective colours and numbers to suit the Glover cables, in which the positive is red, control green, field black, and negative white, assuming as I suppose we may, that this particular chassis has the Glover cable. If it has the Lucas cable, then the colours will not be according to the labels we have put on, but to the colours on the terminals themselves. You will no doubt be arranging for the necessary pulley and suspension. EFC. | ||
