Anybody ever had a stock 60 alternator's output turned up a little? I've been to a couple shops and they both said they couldn't do anything with it, but one said he had some other cases that mount the same he could build for me at 80-100amps. I keep seeing that it's easy to swap in a gm alternator but I can't find one that fits. I just ordered a new stock one with dual pulleys so I can do without the smog pump tensioner, I'd like to keep that but have a little better output.
First guy looked at it and asked me what kind of tractor it came off of--I took great pride in saying "a Toyota FJ60"

Northwest Power Products/Wrangler NW built me a 175 amp unit using a stock 3FE case with an undersized pulley. I've got ~17,000 miles on that unit. If wasn't cheap but it works very well. Charges my dual batteries, dual SPAL 11" high output fans, all lights, my amp and onboard PC without any problem.

If you want a higher output unit return what you bought and have a shop do a custom build (or order from Northwest Power Products).
 
That's the thing, the local shops basically said they couldn't do anything with the stock one. Is there a way to put the 3FE one on the 2F if you don't have a smog pump? That would actually be great because then I could put a York compressor where the stock alternator goes...that would be sweet!
 
would love more info on your rig and the onboard pc. post

mean green alternator was the big purchase I made right when I got my cruiser. the stock one was burnt up and I wanted something with heft to it. it was expensive but it ran my two amps and the rest of my stereo equipment really well. I see it as an investment if I want to have a lot of fun electronic toys in the future when I become a millionaire somehow. it's obviously not for everyone though.

the alternator has a different mounting plate than the smog pump. this is attached to the frame under the motor mount on the driver's side (US model) of my FJ40 - don't know about the 60.

i went in reverse, I got the air pump & mount off a US 40 and moved the alternator to the top like the US 60's had it (out of the water).

So if I got the plate off a 62 would it bolt up? Only water that'll get to mine would be from a hose:D
 
From Specter Off Road:

"Why Specter Off-Road Does Not Sell High-Output Alternators

Specter does not offer high output alternators. We have determined that our customer's needs go well beyond a few more amps for extra off road lights.

These days our customer's power needs can include on-board computers, inverters for 120 volt power, high power communication radios, and state of the art stereo systems. Charging systems to support these devices require more than just a different alternator. The entire charging system needs to be modified to match these needs. Typically this requires changes in alternators, regulators, batteries, and wiring to achieve the needed results.

We recommend that customers who need high output charging systems contact a specialist in the industry familiar with custom charging systems. These specialists will help determine your actual power needs. They will assist you in designing a complete charging system including all the necessary components, wiring changes, etc. This avoids the problems and possible damage caused by too many charging amps for the stock wiring or too many amps for the stock amp gauge. Many times these new charging systems require considerable modification of the original vehicle wiring to complete the installation.

So if you feel you need more power, please consider talking with a specialist before just installing an alternator with significantly more amperage output. "
 
I'm not going to anything extreme, but I am working on a seperate wiring harness/system for anything non stock. A stock 62 alt would probably work fine at 80 amps(goal is 80-100ish)Main thing is I'm gonna add electric fans and better lights at some point and I want to make sure they don't suck all the life out of my electrical system. The harness in my 60 is just as big(wire size wise) as the other vehicles I've tinkered with that put out 100 or more amps so I think for my purposes I'll be fine. No crazy stereos, huge winch, etc.

Generally I agree with this. I run 1/0 cables to both of my batteries through a Painless 250 amp dual battery controller. I also ground both batteries directly to the alternator via 1/0 cables. All of my accessories come off the main battery and the primary leads off the battery use fusible links to distribution points followed by fuses (this wiring does need to be cleaned up and labeled though).

If you need a stock case alt with more power talk to Northwest Power Products. If you want a Ford or Chevy case with adapters try Mechman (I ran one of these for a while but I think I killed it overtightening the belt).

I just got the PC and touchscreen up and running a couple of weeks ago and I flat out love it :D I keep meaning to start a thread on this.
 
I just got my "new" alternator in that has dual pulleys; thought they were gonna be dual stock size but they're dual 1/2" ones. Sucks cause I was gonna use that to replace the smog pump(I had a old gm alternator where it went but it was kinda ghetto rigged and wouldn't stay tight so I'd like to yank it).
