Not sure where to find it...

I have seen several places over the years that offer a high output style that was made for ambulances.... its been a while since I looked but I am sure they are still out there....

200 AMP Alternator

Between xfordtdm and nashvillebill, I think I know what to look for now. Alternators aren't all that complicated and if I can physically fit a 200 to my belt setup, I'll be good to go.

I want to support a 100 watt police siren/PA-System, a compressor to run my air horns and a 100 Amp 110volt AC generator to run other accessories. The 200 should fill the bill quite nicely. IF I can find one....

nashvillebill So...I still have my original alternator after 15 years and 110,000 miles. Would it be cost-effective to rebuild this alternator myself (new rectifier, regulator, and bearing) or cheaper just to buy a rebuilt one from aftermarket store? Am I overlooking any other parts I'd need, and is there anything special about rebuilding it?

p.s. I'm not having trouble (yet) but thinking about future preventive maintenance.

xfordtdm Good question. We manufactured over 100 different 3g models. I don't own my 97 anymore but I think it was 130 amps. This is more than your truck should ever need. There is a bearing cove on the back of the alternator that has an ink jet print on it. It should say the amperage.

I purchased my 2001 with dual alternators. Way overkill.

I believe your rectifier is fried. The plasma coating on the rectifier probably got fried when the diodes cooked. That black crusty stuff is plasma coating. Just get a reman and be done with it.


So what is the biggest alternator I can get and mount in the same place on my 96 7.3 PSD ? I plan to install some MONDO lights on my F250. You know, lights that will simply blow that other driver OFF THE ROAD when I turn them on. (figuratively, you know)

Rockauto.com has a great selection for model year vehicle specific pigtails and factory connectors. They include pictures on their site so you can make sure you are buying the right item.

This company sells parts for just above wholesale and have many places to drop ship these items. I buy all my parts from them when doing sidework. The local parts shops hate Rockauto.

As long as you know what you are looking for check out this CATALOG. It has it but you just need to find it.

HighwayPrisoner dbelectrical.com is a good choice for a new not rebuilt alternator.

Re: Alternator Smoke

the regulator is on the housing after about 95 but I see many different types of equipment at work and very few powerstrokes except mine.

Re: Alternator Smoke

bearings went out in mine last month. I found the best price was Auto Zone. I think it was around $145 out the door for a reman. It also comes with a life time warranty. If you do find one cheaper somewhere else Auto Zone should match it. Good Luck
