Question Odd volt meter reading

Hey guys,

So almost every time I start my truck and it has turned over the volt meter reads an awful low reading. If I turn on the headlights right after starting it they, as well as the dash lights, will be dim for about a minute and then everything gets up to its normal brightness. Is this a pretty standard thing? I know that the glow plugs draw a huge amount of current but I wasn't sure if this was an indication of an alternator going bad. Any thoughts or similar stories?

It's normal. The glowplugs draw a ton of current. They also will stay on for 1.5 to 2 minutes after the key is turned to start (the WTS light does not indicate when the plugs are actually on ... the voltmeter is a better indicator of that). Cheers!
