My landing gear works (slowly) when cord is plugged into truck, but has stopped working on shore power. The 30 amp bus fuse near switch appears not to be blown. Any ideas?
Even when your plugged in to shore power your landing gear still pulls power from your battery. Check your battery I'm guessing your going to find that's it's bad. If you can get your hand on load tester that would be the best way to test the battery.
