IGNITION COIL CASES. ************************* Now that EPO. is in a position to try out electrically the insulation of the coil cases, I consider that it is most important we should put into practice his suggestion that 10% of the coil cases should be sent to EPO. regularly, in order to keep check on the quality of the material received. We know that variation in the quality of the material or the filling may definitely affect the reliability of the coil case, hence the importance of keeping a careful eye on the insulating quality of the coil case material.
