| -12- BATTERY & FITTINGS to LOP F.56808 PAR BATTERY. X 5535. The Battery Box and anchorage have remained in a good condition. There does not appear to be any weakness in the design. The battery has not given any trouble, there has been sufficient current for night driving and starter motor work. The amount of water added to the battery during the mileage has been .1875 of a gallon. ELECTRICAL FITTINGS. COIL to LOP D.72503. X 6058 This has not given any trouble at this mileage. DISTRIBUTOR to LOP D.51618. X 8692 X 5690 The contact points were making full contact and appeared to be satisfactory. The setting of the points had decreased to .015. These have been re-set to .020 otherwise they have not been interfered with at this mileage. The mushroom head of the high tension distributor very easily broke in two when attempting to remove it. The fracture shows it to be made of a different material to standard practice. It appears to be a very coarse grained material. DYNAMO. 48 coil armature. Higher output type, suitable for Half Charge Scheme. X 6005 The dynamo output has been sufficient for night driving of approx. 4 hours each run. There has been no failure of the lights. The dynamo cuts in at 17 mph. Its maximum charge during the day is 6 amps. With all lights, windscreen wiper, facier lights, there is a nominal charge of .5 of an ampere to 35 mph. At 40 mph. there is a charge of 1 ampere. At 60 mph. 2 amperes. There has been an audible brush noise that could be complained of from the control brush. STARTER MOTOR to LOP D.51632. X 3587 The starter motor slipped intermittently during the first part of the test. This has been cured by the fitting of a stronger friction spring, which is now standard. BODY SUBFRAME to LOP F.56927. The body subframe and anchorages do not show any weakness. We had a bad scuttle knock at first which was found to be due to tightening up the rubbers between the dash and scuttle too tight which caused the bottom to knock. WING & WING STAYS N.S. 3089. STRENGTHENED TYPE WING STAYS to N.S. 3089. The front wings have broken away where attached to the running boards. This is a re-current complaint. The wing stays do not show any fracture at this mileage. | ||
