Upgrading the alternator??

You could try http://www.mechman.com/. I'm running one of their 175 amp alts in my FJ-62. It's based on a Ford case. They turned down the pulley as small as it could go without the belts bottoming out to help out with idle output. This helps but not enough when I'm running a lot of accessories at idle.

My plan is to flip the A/C idle up circuit in the ECU based on a voltage sensing switch (below 13 volts apply voltage to the A/C pin to kick the rpms up). At A/C idle (~850 rpms) I get 14 volts with lights, wipers, heater on full... Unfortunately I've had too many other projects going on to do more than just test the circuit and confirm that this pin just see battery voltage when the A/C compressor clutch is engaged.
 
Not sure yet, but this looks like a good bet:

I will do some measurements over the weekend... hole to hole and ask about the pulley. If the holes line up, then it is just a matter of a small spacer for proper alignment.

The outputs are more than enough. Check it out.
 
Just got this e-mail reply. He sent me a quote as well. Will post the details later:

Hi Ron

Yes we offer a 200 amp Denso for that series that we sell quite a bit of. Bolt in/ plug in..........It's actually sold through our HO division. I will have Rick Neice, head of R&D for HO call you. American deals primarily in truck and heavy duty chasis products that would not fit as cleanly as a Denso would.

here's the link fot the site....

If you could provide me with a phone number we can get started.

Thanks........

New Siennas come with 150A stock alternator - worth a check?
 
Yup, i just got the same one!

Sorry, cant justify this mod to myself! I will deal with what i got!

The stocker is 80amps on the 93 right?
 
The stocker is 80, and you will probably have no issues with it. A good 130 amp Tundra unit can be had for under $100. I scored mine on car-part.com from a wreck with 3k miles for $100... looks new.
 
Looks good, but$

Of course, what I'm looking for is plug a play. With the type of batts I'm running, I like the set point at 14.4 volts, although I would prefer around 14.75 volts. Will have to talk to these people and see if this perimeter is adjustable.

I think I'll go with the the quote I've got and then pray a lot. I've got alot of crap hooked to the battery.

I got a quote from the HO people. It's a 175amp and they want $650 for it. :eek:


Arya,

Alterstart makes a 150 amp. unit (all new) Nippondenso, for about $250.00

I have posted it here before. IIRC it produces 75-80 at idle, and has a limited lifetime guarantee.

I am not affiliated with them in any way. I have a couple of their HO alternators on other vehicles and have been very satisfied with them.

by the way, does anyone know what is installed on the new FJ?

Larger case with bigger fans and other components make this a nice unit. Pully bolts up.

Offset of the lower mount is perfect.

No picture of the upper mount, but the pulley side offset is correct. Mount is deeper. Third ear mount could be easily removed if required. Plug on the back has 4 wires instead of 3, 4th wire for....???. Main charge wire will bolt up. Looks quite do-able with minimal or no mods to the alt. or brackets... as soon as I find all my bracketry it will get test fit to the engine.

Thanks for the info Brian. I'm not in a rush, so I think I'll wait to see what you come up with :D

Thank god there are people out there that are smarter than me or at least have better resources than me to figure this @&@&@&@& out. If ever meet any or all of you, the :beer: is on me! :cheers:

Brian, did you ever make any progress with this? I'm debating doing some R&D on this myself, since I feel that R&R'ing the stock alt isn't going to suit my needs for very long with all of the electrical accessories I've got going on.

Thanks,

Ary
