I have a 2000 Yanmar vio 70 that has no hydraulic functions except the tracks and blade. I believe it's something to do with the lever you put down that should activate the hydraulics because it starts with the lever down. Where should I start? The diagram I have doesn't mention the switch located in the console for the safety switch and the switch passes a continuity test. Is there a relay for that switch somewhere?
So lets see your diagram?
The switch is just part of the system that will operate an electric/hydraulic solenoid valve. Have you checked the fuse panel for blown fuses?
This is what's in the manual
Pretty sure it's the one labeled "Safety Relay".
After tracing the diagram it doesn't seem to go to any hydraulic solenoid or the console switch so I'm not sure if that is the right relay
There is a cut off switch on the top of the page 1, also a cut off solenoid at the bottom of the same page. It looks like power is fed from a fuse in the fuse panel.
