Northstar Boating - Recent Questions, Troubleshooting & Support

It appears that the back-light, a Cold Cathode Fluorescent Tube about 3mm diameter, is not working. There are two likely causes. 1. Tube has failed. 2. High Voltage supply circuit has failed. I'm currently pulling my unit apart to determine the cause. I suspect the tube is the problem but I will post more when I have it apart Does anyone know what the correct operating voltage of this Cold Cathode Fluorescent Tube is? Northstar could not provide me with a service manual. The screws are 1/16" or similar Allan Screws (about 1.6mm internal between flats). They usually can be undone with a 1/16 Allan Key but some of the screws can't be unscrewed with this key. I'm having difficulties uploading the photos at the moment but I will try and fix that.

i have the same problem there is a resistor on the high voltage side burned cannot identify the number or resistance to replace it need diagram or parts list for machine

yes you can you need power lead and 12 volt battery

If it is connected to the boat motor check the voltage that is coming from the engine and clean the battery post. This solved the screen flickering.

If you don't want to do that just call Northstar customer support and see what they suggest.

From the owners manual (page 78, link below) NMEA out (+) is the white wire and NMEA (-) or ground is the black wire. -Steve http://www.northstarnav.ca/upload/Northstar/Documents/EXPLORER_650.pdf

The closest I could find was for the Navman 6000/6500 models. See the link below. Hopefully it'll be of some assistance. -Steve http://www.navmanmarine.net/upload/Marine/Internet_Manuals/6000/6500_MN000239A_eng_web.pdf

Hi Robert As this is a discontinued product, I would suggest you contact the manufacturer directly using the link I've included. Most, if not all transducers are made by Airmar so I expect you'll get some joy. Hope this helps -Steve Contact Us Northstar
