Thanks for the input... had problems when catalytic converter went bad, computer put rv into limp mode and Good Sam had it towed to nearest shop. while there asked to fix the turn signals. when I got home checked camera no picture, no power to monitor. the fuse in the fuse bank is not blown. The RV repair shop is over 100 miles away.
someone in this forum or one of the others forums stated the difficulty in accessing the inline fuse near the monitor. no way no how can I reach it without removing lots of stuff. there are three cameras and all are just as difficult to reach. was hoping if I could just remove the monitor I could then check for any inline fuse, check the camera, check the monitor or the wiring without removing half of the dash.
