If your Dual Marine Equipment unit isn't powering on, several factors could be at play. First, check the yellow and red wires to ensure they are properly connected and receiving the correct voltage (11~16VDC for the red wire). Also, verify that the black wire is securely connected to ground. Finally, inspect the fuse and replace it if it's blown.
