Why won't my Dual MXD55 turn on?

Your Dual Marine Equipment might not be turning on due to several reasons: * The yellow or red wire may not be connected properly, or the voltage is incorrect. Check the connections to ensure the voltage is between 11 and 16VDC. * The black wire may not be connected. Check the connection to ground. * The fuse might be blown. Replace the fuse.
