Problem with not dropping to 6V when connected to a vehicle
1. +- 12V goes back and forth, and with a 1GS/s oscilloscope, other companies' products show +-12V normally, but the PWM we made does not show normally even at the same 1GS/s. What should I look for? See Attachment.
When the scope is set to 100ms or 10us, the waveform is normally shown as 1Khz.
2. It is normal up to +-9V, and then PWM is sent with a duty of 26%.
The S2 switch must be closed normally in a vehicle, but why is it not closed?
