Does anyone know a fix for a non working depthsounder? I have a 2006 40 sundancer. The water temp display does not work as well. Thank you. Rick J

Is it's connector at the engine harness a flat 4 pin connector?
If so pins A and D should have 5 VDC (if I remember correctly) across them. Use caution not to contact any other pins when making the measurement. Pins B and C connect to the CAN H network and are the data conductors.
