Excessive grid heater cycling?

Last night while in the drive through I was getting a quick bite to eat and I usually shut the engine down so the drive thru person can hear me correctly. Well, it was somewhat cold, probably in the high 50s or so and when I turned the truck back on waiting for my food at the window, I noticed that my grid heater seemed to be cycling quite a bit more than normal. Usually when the engine is warmed up and been running it never really does that, but could I be looking at ny potential problems with this? I am very sure it was the grid heaters cuz I was not running any air or heat in the truck(had a pretty heavy jacket on) and the volt meter would drop below 14 volts when it happened and the head lights would dim out some. The alternator is acutally pretty new as my stock one went out at about 150,000 miles and I got a remaned Denso from Napa in there right now.
Please, let me know if this is normal or if I should look into it before my Xmas vacation trip tomorrow, TIA.

Joe
