Common Checks and Troubleshooting
Please use the following suggestions to troubleshoot problems with your unit.
Check the Unit
Using the Setup Menu tab, set all features to "Auto" or "Restore Defaults."
If possible, test the unit on another boat with the same model number and accessories installed. If your unit functions properly on the other boat, you know the problem is in the installation, accessories or cables.
Check the Connectors & Pins
Check the pins of all connectors, to make sure they have not been bent, broken off or pushed back into the connector plug. If any connector pins have been bent, you may try to straighten them with needle nose pliers. If any pins are broken, replace the entire accessory. Note: There is a risk that while straightening a bent connector pin, it can break.
Check the Cables
Check all accessories and cables for nicks, cuts, or physical damage. Try to repair any nicks in the cable with electrical tape. If any cables have had the internal wires cut or separated, the entire accessory or cable should be replaced.
Check the Accessories
Unplug the transducer and all other accessories, except for the power cable, going to the fishfinder. If the depth sounder now operates properly, reconnect the transducer and accessories one by one until the problem returns. Replace the accessory that is causing the problem.
Check for Proper Voltage
Check for proper voltage to your depth sounder at the connection to the battery or at the fuse panel. This will ensure that you are getting the proper voltage to the fishfinder. The operating voltage range is shown in your Operations Manual. It is advisable to check the voltage (http://forums.sideimagingsoft.com/index.php?action=dlattach;topic=2983.0;attach=4938;image)with all of your electrical equipment running as well as with the main motor and/or trolling motor running at different speeds to insure proper amperage. This may show an over-voltage, under-voltage or electrical interference condition. If you have an over or under voltage condition, it may be due to an inadequate charging system on your boat. Have your boat's electrical system inspected by qualified personnel.
Check for Electrical Interference
- Check your depth sounder with the boat sitting still, with all electrical equipment and motor(s) off. This will eliminate any possible source of interference. If this corrects the problem, then the fishfinder is receiving electrical interference from your boat equipment.
- To determine the piece of equipment that is interfering with your depth sounder; turn each piece of equipment back on individually, until the problem starts again. When the problem begins again, the last piece of equipment turned on is interfering with the depth sounder. Also try this with your main motor and trolling motor running at different speeds. Follow the appropriate instructions to eliminate this interference.
- Using an in-line fuse, connect your fishfinder directly to the battery. This may eliminate faulty electrical connections and electrical interference, which may be causing your problem.
- Have your boat's grounding system inspected by qualified personnel. Your depth sounder may be trying to operate on a "floating ground".
