We have had further failures of the dynamo owing to the above, and as I previously pointed out, I do not think it is the fuse which "blows", but actually breaks due to faulty fixing or vibration, or the wire itself not making proper contact. I feel sure the wire is much too fine, and should be replaced with more substantial wire which can be properly coiled, and at the same time, has the same characteristics as the present wire as regards its carrying capacity, as from our experience with these fuses, I feel that similar faults will take place on customers' cars delivered. I should be glad if you could let me know what could be done to the cars now on test, i.e. how an improvement could be made, also whether in dealing with cars delivered we could also supply different fuse wires as above suggested.
