I have 2010 Thomas front engine pusher . There is a alarm on the fuse panel for the roof hatches . It won't shut off . I am showing that there is a ground fault in the system . I cut all the roof hatch wire connectors and that didn't stop it from buzzing . . We have been having issues with the door buzzers not working and blowing the fuse . Fixed that . I can only think to rewire the hatches and relocate the alarm . Any other ideas ?
