The round pads that are near the transistor connect to the transistor. The square pads should not. When the round pad got ripped off it did leave a hole that looks square though .kylejohnson wrote:When using a multimeter I miraculously find that the connections for the M3 wires are still working, except for one: square pad to transistor. I am hoping someone more knowledgeable could instruct me as to where I could connect a patch wire? Or otherwise help me figure out why square pad to transistor connection is not working? M3 Square pad to +BATT works and M3 Square pad to circle works, so some parts of the M3 square pad are ok ok. Here are my readings, with photos..
What about the other side of the pcb? Is the M3 round pad ripped of there too? If not, when you solder the wire in the hole you can try to bend the wire over so it touches the transistor pin and then solder it to the pin also.
