Appendix B - Troubleshooting

This troubleshooting guide is written with the assumption that the user has read and understood the relevant sections in this manual.

It is possible in many cases to solve difficulties without having to send the display unit back to the manufacturer for repair. Please follow this troubleshooting section before contacting the nearest Northstar dealer.

There are no user serviceable parts. Specialized methods and testing equipment are required to ensure that the display unit is reassembled correctly and is waterproof. Users who service the product themselves will void the warranty.

Repairs to the product may only be carried out by a service center approved by Northstar. If the product must be sent into a service center for repair, it is essential to send in the transducer(s) at the same time.

B-1 General problems

1-1 The 657 won’t turn on:

aThe 657 is designed to operate on a 12/24 volt battery system, where the voltage may vary from 10.5 to 30.5 volts. If an excessive voltage is supplied, a fuse will be tripped, turning the display unit off. Check the fuse.

bCheck that the power cable connector at the back of the display unit is securely plugged in and the collar is locked in place. The collar must be secure for watertight connection.

cMeasure the battery voltage while the battery is under load - turn on some lights, radio or other electrical equipment connected to the battery. If the voltage is less than 10 volts:

1-2 The 657 won’t turn off:

The 657 may have been wired for Auto power. In this case, the 657 cannot be turned off while the ignition power is on (see section 2-2).

1-3 If the 657 beeps when turned on but nothing is displayed:

The 657 may be operating, but the backlight settings may have been set too low (see section 2-3).

1-4 The wrong language is displayed:

See section 17-1.

-the battery terminals or wiring on the terminals may be corroded.

-the battery may not be charging correctly or may need replacing.

dInspect the power cable from end to end for damage such as cuts, breaks, squashed or trapped sections.

eCheck power wiring (see section 18-4).

fCheck for corrosion on the power cable connector and clean or replace if required.

gCheck fuses that are placed in line with the power cable. A fuse can be blown despite appearing to be good or the fuse may be corroded. Test the fuse or replace it with a fuse known to be good.
