First cold morning start

Well the temp was 28 this morning. The first what i would call cold start since I bought the truck. turned the key and waited for the wait to start light to go out. Started fine. However for the first 2 minutes of running the Volt gauge would cycle down to say 10 volts and up to normal. My guess is the air heater cycles off and on when cold. Is my guess correct or what else is happening. So much for fall. Its snowing in Chicago as I type this. Right to winter.
