| X5783do EFC. 17.5.28. DYNAMO 1696 (20 H.P. 57 coil) I have seen this dynamo in Mr. Brock's Dept. It is said to charge OK. but the commutator requires truing up. The connections to the comm. have been resoldered outside. Probably the fault was throwing of solder due to cutout failure. EFC/F.J.Allen. | ||
