View Full Version : Yamaha Gauge amp New Lowrance HDS8 Not Communicating

10-18-2009, 09:22 AM
Just installed a new Lowrance HDS-8 unit to my boat. My existing Yamaha Fuel Mangement Gauge will not respond to the Lowrance Unit. Swapped the Fuel Management Gauge with a stock Speedo Gauge and still no readings. Lowrance unit does communicate with Icon VHF Radio. Unit is wired as Lowrance instructs.
