Along with all the advice already given to avoid voltage drop, check for any chart plotter wiring run close to high current wiring.
On Calypso, some sensitive electronics have had issues if I ran any of their power or sensor cables/wires very close to the engine starting or charging circuits. Once in a while my cell phone will freak if I lay it close to those same cables and start the engine. Calypso does have separate start and house banks but there is a concentration of 00 gage battery cables in several areas between the battery banks and the engine space.

Cat's Paw's batteries are quite new, fully charged, and hold their charge well. But obviously the voltage drops when cranking the engine. None of my other electronics is affected this way, including an old CP 150 Standard Horizon and a 2007 CP300 chartplotter. Apparently the E7 demands a higher voltage to keep from crashing. Best way to deal with this? Others must have a similar problem. I could put a small rechargable battery just before the panel switch to the E7 with a diode to the main battery, so it is kept charged but maintains enough voltage to the E7 when the main voltage drops. But I bet there is a better solution. Suggestions welcome!
