Dear guys, pls help me with this issue:
I've got three NavNet 7" GP1810C display with a router that interfaces all the 3 displays together. The center display turns off automatically (it does appear on the display: 3 sec.... 2sec.... 1sec..... and turns off) just like you want to turn off it by keeping pushed the power/brill button. But it does it by itself....
Batteries have correct voltage. What can I do in order to eliminate this problem? thanks in advance
ben
check to see if they all have the correct power and the power is clean and fuse's are the right size. Just for an example: while crusing at 27 knots on one of the boats I run we are heading out on autopilot .. things are great, nice day, not even a wave... then the boat takes a hard port turn...and keeps going port. turns out the auto pilot compass is screwed down by the head pump motor which in turn ..turns the boat hard over. Goffy ass stuff happeneds on a boat like this sometimes so just trace down the wires and see yourself if they are shared / loose wires / grounds are good / etc. if not call a electronics guy out to check software and buttons on the machine.
I'd be willing to bet you have a bad connection (corrosion) somewhere. Checking with a meter, you have voltage, but there is no load on it when doing this---- as soon as the unit's load is put on the circuit there is not enough connectivity (sorry I know that is not the technical term) to power the unit. Think of it as an engine with a pinched fuel line--- it'll idle ok, but not enough ability to supply fuel under a load.
I had this same problem on my sonar and it drove be nuts until an electrician friend took 2 minutes to figure it out.
X QUESTSPORTFISHING: all the three displays work on the same battery. the display that turns off is the one on which the radar dome and the gps antenna are connected. the other two, communicating through a router, don't turn off.
X GLENN W: yes I think also, it can be a corrosion problem or a loss of power somewhere throughout its cable circuit, I'll check it out
the other thing I see is that: when pull and insert again the fuse of the display, the unit turns on (I can hear the "beep" sound) and it turns off again... do you have some ideas about this phenomenon??
thanks again
the power feed that runs a radar is very important ... make sure you have it fused properly and the draw on the wire is a lot more than just a gps head. start tracing down the system and make sure you have at least a #10 wire even if the run is short. longer runs take bigger wire. remember to check all screw connections also! get at it the fish are waiting in line!
