Hey guys, I'm building a light bar for my track/kick and want to upgrade the alternator on it.  I searched and found a lot of info, mostly just generic. Did find a few brackets out there for it.  I'm gonna go with the Trail Tough lower bracket, but I need to find out from someone who has actually done this swap what vehicle application the alternator was originally from.  I really want to run the 105amp GM alternator (popular  in the later 80's and into the 90's).  I know S10 Blazer's have them, Beretta's have them, etc.  But there are like 20 or 30 different model numbers of different 105 amp Alt.'s.  I also read from someone (will have to go back and search again for who said it) that it needs to have the correct regulator.  They said it needed to have a regulator model # D10SE12.  They started out with one with the wrong reg. and it killed the battery.  After they figured out what it was, it was a $4 fix.  So any help is greatly appreciated with this swap.

Thanks in advance,
Bryan

I'm going to buy a rebuilt Hitachi Alternator and have it recoiled to put out more amps.  If I'm going to install extra electronics, I'm going to need more juice.

So I too would like some help on this subject.

I like the Pep Boys replacement warranty so I told them I need an alternator for an 86 suburban 350ci, 4x4, power everything, A/C. This ensured me I'll be getting the high output alternator. No problem running 2 100watt hellas, 100 watt backup light, highbeams and heater fan on high and still putting out 15 volts at idle.

Keeps up when using the winch too.  

OK cool. 86 Suburban 4x4 350ci...

Anyone know if the same ones will work in both sami's and kicks...

Keep 'em comin' guys!

alt# 7-69035-20436

I used one from a 80's camaro with a 2.8 95amp got it from NAPA in my sami should work on the kick too go to roadless gears site figmo has a write up on the wiring

alt# 7-69035-20436

And what number might this be from?  Manufacturer, Pep Boys, Advance Auto Parts, Napa?  That's why I asked for applications...

I work at a company that rebuilds sterter and alternators. The D10SE12 is a 10 SI type delco this was on older cars and trucks but the SE means self exiting. You will only need to hook up a battery cable and go. It requires a little wiring but the smaller case CS130 is rated at 105A and fits the same lower bracket. This unit was in early 90's gm cars and trucks there is basicly three main configurations and they are top ear at 12:00, top ear at 10:00 and top ear at 2:00. there was minor differences like clocking position but most can interchange each other. I used alternator Delco # 10463150 or lester # 7964-11 most parts stores will be able to cross these # into their own. I used this # due to the offset and clocking configuration. you will have to buy a new reg plug but it will wire up if you decide to go this route I can help you wire the new plug. PS my unit was rated at 105A but it actually puts out 118A. Way more than the 78A unit in the 10SI unit suggested. Also the stock charge light will still function. I have a large stereo and needed max output.

I'd suggest you read through the following links ...

I too have this mod on my "todo" list ... probably going with a 94a 12SI three wire when I do it.

Sounds like you're the man I need to talk to!  So you actually run the Delco # 10463150 and it works fine, correct?  Is this in a sami or a track/kick?  Does it matter?  Also, where would I get the new reg plug for this alternator?  Thanks for the info.  My dad manages an Advance Auto Parts store so I'll get him to run that # and see what he can do.

Thanks again!

Also, did you use the pulley that came on it, or did you have to switch the stock pulley over to that alternator?

this might work, but you would have to change the pully and buy a alt bracket.  i ordered one from T.T. today, now waiting to find an alt. :-/

Here is a lay out I've gotten off this board with some picturs for a GM homemade braket.

t.t. alt bracket in the mail.  so i called oooreileys and they cant a delco alt anymore.  so i used the info on the mad electric site and am getting a 94 amp one from the yard tomorrow for $25 (the 12si one).  then just have it rebuilt for $60.  the other option at Ooo was going to be $95 for a 94 amp one.  will prob get the mad wiring kit too.  $27 for it aint bad.  then i can hook up my lights on the roof rack

rebuilt 12si's at napa are $40 aren't they? (94amp)

(or jc whitney?)
