What are symptoms of a bad switch?
When I insert the battery to my Milwaukee 2753-20 the light on the tool comes on and the tool makes a high pitch sound. It sound like the trigger is pulled just barely, but I’m not touching anything. The button to switch modes is lit up but will not let me switch speeds. It will switch direction from forwards to backwards but I’m stuck in speed number 1. I pulled it apart and the switch is measuring about 3.5 to 4 M Ohms across the blue and red wires of the switch. Maybe the switch is not opening back up completely and keeping power going to the motor? What are some other troubleshooting steps I can do? Anyone else had this problem and found a fix?
