I just redid the wiring for my Helixg3 mega si unit with 14gauge tinned wire for the console direct to the battery with 4amp Mel fuse. Did the Same thing with a helix G1 at the bow. At the bow voltage on H1 reads same as battery, 12.8 volts. On the newer unit I read 12.1 volts, but checked the pins at the connector and it has 12.8 volts. Also the head unit is clicking fast for 5 seconds and then slow for 5 seconds. It is loud enough to hear with no noise around, but easily drowned out if wind or motor on. Clicking isn’t there on startup screen, only after I clear that screen and then there constantly.
What is causing this clicking or is this normal? I read that the voltage may be off on the screen, but this seems to much. Any thoughts?
The reason I made the wiring change is because I was getting a little flickering on mega si when I had higher contrast so I assumed clean power issue because I was using the console fuse block
