| 86044 Hs{Lord Ernest Hives - Chair}/Wst.3/MA. 31st October, 1933. Messrs.Joseph Lucas Ltd., Great King Street, Birmingham, 19. For the attention of Mr.Robinson (Laboratory.) Dear Sir, We are sending you, attached herewith copy of the tests we propose to carry out at our Works here on every C.A.V. Regulator unit received. We should be much obliged if you would peruse this specification and let us have your comments on the same. As a matter of procedure and for the safe-guarding of Rolls-Royce products we invariably carry out similar production tests on all accessory pieces of apparatus. We also return for your personal attention a C.A.V. Regulator type B2H1 number 15128. This regulator appears to be out of adjustment on the second stage regulating contact. When first tried the regulator, on the shunt winding only, operated normally on the first stage up to the point where the resistance is continuously in circuit, after this the dynamo voltage was permitted to rise with every increase of speed. After gently shaking the regulator it was made to operate on the second stage at 17 1/2 to 18 volts shunt winding excited only. It would thus appear that this regulator is faulty and we would like you to have the same checked and readjusted and then returned to us with your remarks. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
