Does anyone know if our trucks ever came with a second alternator, or just the 215A single?

Mine shows an optional second alternator on the belt routing sticker on under the hood.

Mine had the tensioner TSB done before I bought it, so it has a superduty tensioner. I suspect the dealership
also slapped a superduty belt routing sticker
on it.

It would be really nice to just put the second alternator on for charging my camper and have a totally dedicated charge circuit. Yep, I know the factory duals have a PCM control on the second alternator, but if the two systems are not interconnected, I can wire the second alternator to just charge the camper battery so I won't have a problem with the two interacting.

 

the ambulance package came with dual alternators and you could special order it. not really needed unless you are planning on putting lots of lights or a killer sound system in the truck. adding the second alternator is a peice of cake

 

Thanks coonhunterjoe.

Do you happen to know if the Superduty brackets will work, or do I need one specific to the 94.5-97 trucks? Any suggestions on how to get one?

I'm interested in a separate alternator because I have a massive battery bank in my camper. Right now, the truck voltage won't come up for a good hour if I've run the camper battery dead. I'm sure a single 200A would pull it up faster, but I figure it'd be nice just to devote one to charging the camper up and the other would run the truck like normal.

 

The SD brackets won't work cause the alt and AC are switched around compared to the OBS so I guess you would stuck with getting the correct passenger side bracket for your engine.

 

The amblance package had two alts.? I thought it was just one 215 amp alt.

 

That's what I'm trying to figure out here. I've got conflicting information. I have a '95 Ford shop manual, and the wiring diagrams show either a single 130 or a 215. No mention of duals.

If the bracket isn't available, I'm thinking of fabricating one to hold two alternators side by side. Right now I've got a coolant filter mounted beside the alternator, but I can relocate the filter back.

 

Yeah I have seen one van with dual alternators but it was a handicap van that may have had a custom set up on it. The van was a 95 I believe but I can remember if it was facotry or not. All I remember is the 2nd alt was in the way for a simple CPS change.

 

I worked on an ambulance once that had 2 alternators. The second one is accessable from under the truck.
