I have installed the Spy Hunter Switcher adapter from Arcade Shop and the directions mention that if you have a bad hum to install a 4700u 25V or greater capacitor on the +12 and switcher ground. Do they mean to install two on in circuit with the +12 and on on the ground circuit or do you install it with one end on of the cap going to ground and the other end to the +12 circuit? I am wondering if anyone here has done this before and they can elaborate on the directions. Thanks
