voltage drop, Gryphon resetting?

I'm assuming here that your alternator and battery are both good. What do you see on the Gryphon when you monitor charging voltage? I see something in the neighborhood of 14.1 volts when driving during the day and not towing my trailer with its two additional batteries (that drag the voltage down).

When I checked the OBDII connection it did appear to be tight but I'll try unplugging and replugging it as well as remove it from the pod and make sure I have a good connection there as well.The battery gauge seems to be showing everything is charging but I'll set up my Gryphon to monitor voltage in the morning.

It has happened once or twice before but tonight it happened 5 or 6 times in a 150 km trip. I don't know if it's relevant but I have only noticed this happening at night.

I have a 300 km trip tomorrow so it will give me a chance to see what happens. Thanks Jack, appreciate your input.
