I installed a Yamaha OEM 12V plug. Found the connector and plugged it in and put the sled back together thinking I was OK. No power. I see in the instructions item nine listed as "main switch". My fault for not seeing this. Looks like another connector in the drawing. Is this "switch" normally together or do I have to get back in and connect it. Or did I blow a 3A fuse. Shield and cord works fine on my cats. Tested with fluke also. Thanks!
