So today I found my multimeter and opened the BM Dosser. Pump/motor #2 does not work but switching the port at the mainboard, the motor/pump works so it’s not the motor itself; tested for voltage at the three ports; pump 1 shows 11.5v when turned on; pump 2 shows 12.1v and pump 3 shows 11.5v Logic tells me if there’s voltage, by just plugging in the little motor, it should work but it does nothing. Any suggestions on what else to test? I checked the resistors’ ohms and they all read ok but with the caps, diodes and ic’s, not sure what or how to test on the meter. Any help/pointers, much appreciated.
