NavNet vx2

[braydenmeierhoff]

Installing a Navnet VX2 into a boat for a customer. He took all the electronics off of his new boat and wants them installed into his old boat since he is upgrading the new one. Does anyone have a wiring/installation diagram? Ive never played around with furuno and when he took it all out of the old boat he just cut everything and left all the old cables in the other boat. Will need to get all new cables/wiring also. Below Ive attached a list of all the stuff that he gave us in boxes. Thank you in advance.
(x1)Processor Unit RPU-015
(x2)Power Supply unit PSU-005
(x1)Network sounder transceiver unit ETR-6/10N
(x2)C-Map NT max RDP-149
(x3)Multidisplay RD-30
(x1)Control Unit RCU-017
(x2) Radar antenna RSB-0072 (have a 4' and a 6'. will only be using the 4'.)
(x1)Sirius Weather unit BBWX1

If they have a PSU005 that means they have a 1954C/NT radar. I would recommend going under our website and downloading the install and ops manuals for the 1954C/NT (c-map version) . Page S-1 is the interconnection diagram.

We have the 1954C/NT system. We bought it new back in the day and when we an active dealer. We recently replaced the scanner motor due to slight water intrusion from the antenna seal, and are now we are not getting targets on the display. We are trying to troubleshoot the problem and wondered if there ever was a flow chart to diagnose the problem. The unit is scanning but I don't think it is putting out any power from the antenna. I have the installation instructions etc for the system and power supply. As you know there is a potentiometer on the board of the Power Supply to adjust the intensity of beam while observing the targets on the screen. When we adjust that pot nothing happens. We cannot find any old techs here in the venice of america anymore. Most are my age and won't or can't climb higher than the flybridge to get to the array.
The techs at Marine Tech here in South Florida say if the pot doesn't do anything just put it in the middle of its range and call it a day.
In any case they do have parts for these great units. I'm just trying to figure out it my problem is in the antenna up top or the power system. Seems to me it would be up top since no fuses were blown in the supply and the water intrusion was up top. But I just would like to prove with a meter, what is failing before I spend all the labor and money on replacing major assemblies.
Thanks for listening an you help. David
