KLAXON WINDSCREEN WIPER MOTOR OF INCREASED POWER TYPE EKDRG.1. We have now tested this motor and taken characteristic curves of performance of the same. This motor has certainly more power than the original motor and is compound would whereas the old motor is a plain series motor. The current consumption however is slightly heavier and the motor of course has additional weight and bulk. Are Messrs. Klaxon seriously considering substituting this motor for the existing one? as we have never had any trouble or complaints that the existing motor is not up to the job.
