I replaced my sonar unit up front recently and used the same wiring running back to the auxiliary power panel. When I crank the big motor, the sonar cuts out. The old one didn’t. The console sonar trips to (low voltage), but my thought is that’s because I have my voltage warning set to 11.5 volts. Any thoughts on what may be happening?
