I have a Great Dane Surfer. When I push the switch to engage the blades nothing happens. Have checked the safety switches, they are working. I checked to see if I was getting voltage to the clutch' but did not get a reading. I traced it back to the relay, there I was getting about 15v on three of the wires and nothing on fourth wire leading to the electric clutch. However, I'm not sure If I am suppose to get a reading on this wire. The wire is orange. Has any one else had similar problems with the relay? I thought I would ask before I went out to buy a relay. Any comments will be greatly appreciated.
