Hey RG,I checked the socket
Hey RG,
I checked the socket using my DMM continuity tester and it didn’t show any bad connection between the pin and resistor. I still soldered the pin again but there was no change in the circuit. I even checked it with another chip just to make sure the defect wasnt in the chip.
When I try to switch all 4 motors on they dont come on (even the working ones). When I cut the trace of the non functioning motor, the other 3 work properly. I then tried connecting the pin and resistor through a external wire but then it shows the same result (i.e. no working ).
Is there some loading effect at the pin that causes the other motors to switch off too ?
