Flashing light on ACC switch

[HotTommy]

I have a 2006 Bennington 2575RL. A new problem arose this summer when I turn on the ACC switch that supplies power to my radio and depth finder. At first I thought there was an intermittent problem as the power to the radio would come and go. But yesterday I saw that when the switch is depressed, the white light in the switch is flashing on about once a second and there is no power to the radio. I pressed what appears to be a CB button below the switch, but it did not appear popped and pressing it made no difference. Can someone tell me what the flashing light means and how I might troubleshoot the problem?

Check voltage first.

I’d check all connections first. Loose connection could potentially cause this.

Check your connections, check for consistent power from the positive feed to the switch. If both are good. Replace the switch.

Yes, it turned out to be an intermittent connection at the battery. What had baffled me is that the on/off was in perfect intervals. No variations. But I cleaned and tighten the connection and the symptom went away.
