Showrooms (Sr is absent) EWFI3/NLG.12.9.35 Re- 70-2S-Dynamo output This car is fitted with a dynamo and standard capacity battery but the owner does a tremendous lot of night travelling and as his car is fully equipped with headlamps foglamps etc. he complains that his battery gets run down too quickly and in consequence when he stops for breakfast after an all night's travelling, he experiences difficulties in starting up his engine, especially during the winter cold months. Would it be possible to supply a special dynamo with an out-put of 70 amperes, and if so how long would it take to supply one. We hope that you will be able to help us out in this matter. 35 amperes. ventilated Cutting in point Slightly higher new regulator "EWP{Mr Punt}" | ||
