I am guessing the 3FE FJ62 alternator is 75 amps? The internal fan 80 series alternator is 90amps and you can trim the 3FE engine/alt bracket to fit the internal fan model. Not sure what the 60 people would do with that bracket setup.

Just called C.P. generator in Fontana CA about having my 2f alt rewired and found out the following for future searches. The external regulator model for 1984 is rated at 45 amps and they don't rebuild it to higher amperage. As of April 2019 a rebuild of that alternator is $96.00 and takes 3 to 4 hours. The internally regulated model is the 55amp version. Having had to replace my voltage regulator once in the past, didn't feel it terribly necessary to price out repairs to a unit I don't actually own. Will be looking at my collection of bits to see if its simply easier for me to get the 3FE alternator and get up to 75amps which would be a significant upgrade to my setup. I'll reuse the pull and fan if necessary from my original alt.

Fj60 alternator brush replacement
hello all, I'm seeking some tech help on replacing the brushes inside an fj60 alternator. I have unsuccessfully tried to purchase the Bosch and some remanufactured units unsuccessfully. Purchase order goes through then bounces back a few days later saying out of inventory. I also have not...

Not sure if I recommended this on this thread yet.....but....if you have not already done so....consider replacing your battery pos and neg cables, starter main cable, and alternator output cable with either 2 or 4 gage welding cables. Upgrade your connectors and clean all of your grounds. This mod makes a huge difference to all electrical in the truck. It reduces electrical loss due to size and also just due to old wires. When ever I do the change I notice all my motors run faster, lights are brighter, engine cranks faster etc.
90 amp alt is non US, requires different drivers side mount... oh wait, that’s for stock application.... I guess once the victor wrench comes out, anything will fit!!!
So here are my photos
existing attachment and ebay part (and part number from package)
Pics of new/reman alt and the capacitor notice

Hi Glenn,
New set up has been functioning great. The alt I received did come with the capacitor. In terms of wiring I essentially just snipped the old connector off and the blue and green(from the new connector) are both connected to the black with yellow striped wire. Then connect the red(from new connector) to the solid yellow. Heat shrinked and called it a day. FYI that extender connector looks more like a fuse link. Shouldn't be needed you already have a fuse link protection near your battery. I guess save that if you ever blow your fuse link should could come in handy.

Spike - no, that came with the Alt. Just an extender - the black part that looks like a fusible is just some sort of wire management. Does have an o-ring so as to keep liquid out of the connector. Believe the coolerman wires only work for AC/Delco conversions, and this is supposed to be a reman ND.
Casey - when you get a chance, can you see if the cap is connected to anything on your case that has a marking to see if my guess of the "E" on the case having some significance.

Oh, and did you get the 'Quality-Built' brand from Amazon, same as others ?
Oh, are you "that" guy??
Yup. From the link Casey posted up. Once I swap out the pulley and fan from a spare, gonna take it to my local store to have them run the diags on it. Figured for a C note, was worth a shot, vs the price to buy one over the counter new.
Glenn in Marana
Nope, thats the other one.

LOL ok troll.. bet you feel pretty good about yourself.. you come on here.. pepper your lame 'I know everything' comments across the forum even when It's not even asked for or appreciated then you go straight to insults?? so thats how you like to live your life.. thats how you spend your day? you're literally the worst.

I’m going to do the 3fe alternator this week.
The question I have is this: can I use my existing alternator output wiring? I’m trying to avoid making a bunch of changes at once and buying all the battery crimp tools to do
My second battery install now.
I’ve got a new fusible link wire direct to the battery. I forget the amperage but it’s all working well.

4g wire with 100 amp Fuse to the pos post should do it.
@NookShneer Did you ever change to a different length alt belt?
I've got a new OEM 80A for a spare, but if my current 120A goes out, I'll just spend the money for a Mean Green at that point and be happy. Though depending on how my current one might go out, I'm VERY tempted to rig up an external rectifier before it fails. I've been eyeballing the Quicktifier setup for years but never went for it. Seems like it would be a great way to extend the life of a high output alternator. Requires modification to install it though. External Bridge Rectifier for a Tougher Alternator
I don't think I ever did. I don't remember what belt i have on there. I have a welder now and will likely just modify the arm to accept a different length toyota belt.
IMHO, Mean Green alternators are more hype than output.
