DS41 Owner's Manual 5 Troubleshooting No display: 1. Check DC power connections and DC polarity with voltmeter. No depth reading (## at all depths: ##) ## 1. Check transducer for growth or multiple coats of paint. Check the transducer cable for cuts and sharp bends. Check that the transducer connection behind the D41is firm and free of corrosion. Erratic readings while moored: Check transducer for growth or multiple coats of paint. Erratic readings while moving: Cavitation (air) under the face of the transducer. Review installation and reinstall if necessary. Erratic readings only while engine is running: 1. Re-route power and transducer cables away from engine, ignition wires and battery cables. Add feed-through filter capacitor on the positive terminal of the ignition coil. Add an alternator whine filter to alternator. When selecting the location for mounting, the following are recommended: · · Controls of the instrument must be accessible to the user. Electrical connections must be routed to the boat system as directly as possible, minimising the length of cable where practical. 2. Drill a 2-inch hole on the instrument panel in the selected location. With the mounting bracket removed, insert the instrument into the hole until the back of the face plate is flush with the outside mounting wall. Slide the bracket over the body of the instrument.
