Re: 2017 Bosch Seat Motor

Definitely a mulitmeter is not the way to check since the pulse is read from the armature and there are 175 pulses for each output rotation. The attached picture is a bench reading from an oscilloscope and shows what you should expect from the hall signal. These chips are pretty sensitive to static electricity so be careful. BTW, my power supply only goes down to 6V but it should be close. Each pulse is around 14ms at 12V free speed.
