Hi All Not sure where to post this question? I have a 2 post Rotary lift SP09 9,000 lb that is 20 years old and stopped working and of course a car on it down on the locking arms. When I push the up button the lift makes a lould hum and dim the lights. Thinking maybe a capacitor on the motor but when I take the cover off just a single wire and its sealed. Do I have to pull the end cap of motor to remove the wires? Just wondering if anyone has experience with this? Thanks Tom
