I have a 310D Sundancer, The engine hatch was working fine but then stopped working. I replaced the switch on the dashboard, I replaced the 3amp fuse , 15amp and lastly jumped the little magnetic switch to the door. I hot wired the hatch so I know that is working correctly. But I'm having no luck and wonder if I can get some directions. My schematic for electrical doesn't show me the 3 amp or rear magnetic switch but it's on the boat.
