Mike72 Posted August 30, 2011 Posted August 30, 2011 My hummingbird keeps either shutting off or locking up while on plane have to shut it down and restart to get working again. No problems any other time. Could it be a wiring problem or a transducer problem? Boat is a Ranger 188vx and the hummingbird is a 567 with gps. Quote
Super User Wayne P. Posted August 30, 2011 Super User Posted August 30, 2011 Where is your transducer installed? How is the unit powered? Have you checked the unit voltage readout when it acts up? It could be the power cord plug to unit receptacle fit, common with that type mount system. Quote
