The Trident Panel has always been switching to Red even when my engine is running and I've plenty of power. But as I mentioned to Ron I'll look closer at the voltage drop and see if I can test it in some way. I don't have a multimeter that records over time the voltage where I could maybe see but my EMON might show a change; kind of doubt it though. And of course if I reset it and then turn the solenoid off for the anchor windlass I get the same effect. Shouldn't really be any voltage drop there or am I missing something?
