Roller bearing now being fitted at one end of armature to replace ball bearing and a reduction in these complaints is anticipated. Three rate charge scheme is now standard on 20/25 HP. cars and should reduce dynamo complaints. Exceptional cases always arise where dynamo output is unsuitable. Voltage control on 40/50 HP. should be great help. Previous Quarter. C.C. 6 5 11) W.P. - 1 1) 12 Six Months. 20 11 31 31 TOTAL EXHAUST COMPLAINTS. June Quarter.
