Radar Shuts Off

I have Raymarine RL70C unit that works great when the engine is running or if the boat is plugged in to shore power. But when I just am on the battery bank, it shuts down almost immediately with a message "Scanner not Connected". I believe that most likely I have a reduction in voltage to the unit that is causing this that is overcome when I'm pumping voltage to the batteries at 13+ volts by either the alternator or the battery charger. Before I take everything apart I'm wondering if anyone has another idea of the cause of my problem.

Thank you in advance for your input.

Re: Radar Shuts Off

Measure your voltage at the battery. And at the power wire connection point. Prefably With unit on. And charging off.
