We should be glad to have your recommendations as to how to meet this difficulty. We might for instance state in the Instruction Book that the battery, even though faulty, should be left connected to the system (though this only includes cases of faults which do not involvë discontinuity of the battery circuit) in which case it is probable that the lights and therefore also the battery ignition could be satisfactorily run, once started. In view of the bracketted cases, it appears that (1) we must either provide some voltage regulating or limiting device, or (2) we must allow and state that in some of the cases of ignition failure, the system is not secure in ordinary hands against further damage.
