Battery meter on dash fluctuates

I noticed the other day when I start the coach after it has been parked for a few days that the battery meter fluctuates from about the 12v area to the 14v area. The needle moves back and forth about 12 times and then it stops and settles in at just over the 13v line. Anyone else notice this happening? Not sure what is happening.
Thanks for any suggestions.
Tom

Mine does the same thing... Then settles out and doesn't do it anymore. Seems like the alternator is cycling on and off when the coach firsts starts up and then it's good.

Mine does the same and if I am parked for more than 3 weeks it will give me the low battery warning also. After a few minutes of running the warning goes away.

JT-
I thought the same thing, that it could be the alternator cycling or I also thought that it could be electrical components coming on line, one after another.
Hopefully it won't turn out to be a problem later on.
thanks,
Tom

Probably makes more sense that the components are
Coming on line. I agree, hopefully this is just normal and won't be an issue later.

Would believe it's the voltage regulator adjusting the current going into the battery.

How cold was it? Did manifold heater light show while you were cranking the engine? If so, the voltage level will fluctuate as the Cummins Engine ECU cycles the heater directly after start up.

Freightliner told me it was normal as the system needed to warm and draws current as it cycles. Made me nervous at first. I hope you had a nice warm day.

Marty,
Thanks for the info. Yes, temp in 70's and sunny. Hope you don't get hit too badly with the storm. Keep us informed.

This must be a Cummins thing, my Berk does it as well as my Dodge p/u with the 5.9.
