IGNITION COILS. ------------- As the result of further work on coils "impregnated" with Seekay Wax the Experimental Department now consider that the slight debit in output when using Vacuum impregnation with Seek-ay Wax is outweighed by the advantage which accrues when the coil is thus effectively sealed. Please instruct the Works to impregnate in vacuo with Seekay Wax all our ignition coils. BY. {R.W. Bailey - Chief Engineer} By | ||
