He wants someone to ask him about the "Specialized Electronic
Equipment" so he can talk about that. This is the second day he's
been looking for an answer. Phone calls to Toyota dealers and auto
parts stores aren't acceptable, just posts to a newsgroup.

I could make a few phone calls and have the answer for him in less
than 1/2 hour, but I'll be damned if I'll do his leg work for him.

Hummmm...I wonder if he's related to the guy who's mechanic stole his
car's AC.

Hi Joe,

Thanks for the response.

Some local Toyota dealers' parts departments have said that Toyota
could not help. Aftermarket-type sources and rewinding-type
possibilities that have been checked so far have come up dry.

Unfortunately, I also just found out that the vehicles in question are
not available in the USA, and are somewhat different from the LCs that
are available here (which seem to all have V8 engines, now, for
example). They are apparently Toyota Land Cruiser "Prada" models,
made in the UAE (United Arab Emirates). They are "4500 EFI GX.R V6 24-
Valve 4x4 gasoline engine".

No wonder all of my domestic inquiries have failed, so far.

Maybe someone who's in the middle east will chime in.

Thanks again.

- Tom

The "Prada" is something like the original Land Cruiser we all love so
much (the FJ40 "JEEP" type vehicle) and has or had a 4 or 6 cylinder
engine, and would not have the part you're looking for. I think the output
on these is ~75 amps.

Even the HO alternator for the Supra only goes 90 Amps. You're looking for
a LOT of juice! Does your equipment need to be operable while the vehicle
is moving? You may have to either think more of batteries or going to AC
with an external generator.

I think the biggest alternator Toyota makes (my scope goes back to the
late 80's/early 90's) was about 110 amps, and I think Nissan had one that
went 120 amps.

You may have to install something perhaps from a diesel truck like a
Kenworth, but you're looking at hefty parasitic losses on the fuel economy.
And you'd have to fabricate a bracket for it and get a belt to accomodate
it.

As far as anything else, you've piqued my curiosity. What the HELL are you
doing?!?!? ;)

Let us know how you make out...


Oh, you may also want to check with a Custom Car stereo shop. Some of
these THUMP machines need some heavy duty current, and with bigger
alternators, gel-cell batteries and 1 mF capacitors can overcome the
current problems when a 60Hz thump blows out the back glass...

Doing Global Warming research, or Hurricane Chasing?

Oh, and I already asked...

If you need 200A hot or better, you are well up in the territory of
truck alternators. Best bet is to find a local (might be 'regional'
depending on how large a town you live in) auto electric rebuilding
shop that deals with truck alternators, take your vehicle there.

They can look at the available space and existing bracketry in the
car, and will know what they can make fit in the space. And work with
the existing vehicle wiring, though you most likely will need to adapt
the vehicle harness to plug into the new voltage regulator.

And you will need a much larger charging output lead going to the
dual (or triple) battery isolator, and then on to the vehicle battery
- some truck alternators already have split diode stacks that can go
straight to two battery banks. The existing #8 AWG lead between
alternator and battery would be glowing red if you tried running 250A
through it.

Note that if you don't have the extra load on-line most of the time
you WILL have problems with boiled batteries. The alternator will be
putting out way too much charge current for one stock battery, and
regular car batteries can't accept a charge that fast. Even with a
dual-battery conversion it might be too much, unless you use the big
honkin' 8D locomotive starting batteries.
