Nope, mine doesn't. I believe that DB has 220amp alts for the dual alt setups- their's is the top alt.Did either of your trucks have the dual alternator setup from the factory?
The second alternator would almost be like a backup if one went bad right? If you're truck didn't come with it, there is a write up on here how to add it, it's very simple.2nd alternator option wasn't on any of the trucks I've bought. Haven't ordered a truck for some years now. I think about it this way, why have a 2nd one to go bad, another thing to move when you're working on these trucks so on and so forth.
I keep a couple of spares around for emergencies but, I haven't worn a nations out yet.
For the record the trucks would run/operate fine with the stock alt. but, BIG BUT not long after snow season they would be done the first time myself or one of the guys left headlights on and the battery got drained a little.
Not to change the thread but, anyone use those OPTIMA batteries, they're not very popular around here, AT ALL! The truck in my AVATAR has one hell of a stereo sys. and I wanted to blame it for the batteries but, it wasn't long until I found out that wasn't the prob because it was happening in my other trucks.
I had the DB alternator in The Pumpkin and have the DB alternator in the Procharged 6.0 truck. Never an issue with either.DB Electric is the alternator that will be in my truck. Right now I'm running a black powder coated 200amp (105amp idle/ 200 at 1200rpm IIRC). I was having battery problems that are a thing of the past. Are you running the Nations 250amp alt for $425
