I completed my install of the ghost last night. I noticed when I powered the unit on for the first time the 24 volts led came on. I hit the test button and it shows the batteries full and tapped it again hoping it would cause the voltage option to blink so I can select 36 volt but it just keeps. I checked the voltage at the power wire connection and I had 36.4 volts. Is there something I am missing. The video I watched and the Operation guide says it should recognize the load. I am waiting for a response from Lowrance
