Thanks for the pointer! I missed that prior posting :?
I found a shop in San Jose, but they are more re-build
to stock spec. did a good job on broken starter for me.
I'll look these guys up and see what trade-offs are possible
for me.

for higher output I suggest you add a second alternator and install a dedicated utility circuit.

Gut in Switzerland offers such solutions

Hotzenplotz,
Excuse me for bringing up this old thread. l am in need of the mounting bracket seen here as quoted in your post. l have a rooftop mounted Webasto acir conditioner that runs from 24V and draws a peak of 68 Amps. l plan to run a pair of dedicated batteried for this, along with a 100 amp alternator like the one pictured here as a dedicated alternator for this utility system for the AC system.

Can someone tell me where to find this bracket? Thanks!

wow.


LMFAO.

My friend posted a few years ago that he wanted to
rebuild his alternator and increase the output. A bunch
of a$$holes poo-poo-ed the idea and told him it just
couldn't be done. They did the same thing to anything he
posted. He left your forum and came to me.

I came here and found the same vitriol. I don't visit
this forum often and only return every 4 or 5 months for a
looksee if anyone does anything actually worthwhile.

In response to the question ... this is easy, easy,
easy. It shouldn't even be a discussion thread. Anyone
who says anything else isn't informed.

Take your existing alternator to any competent
alternator shop and ask them to rebuild it. A nice
cleaning, some tightly wound copper wrap and new
brushes, diodes, etc. will bring it up to about 40 to
42 Amp. The difference from OEM is that the materials
are slightly higher grade than they were 50 years ago.
Total cost - about $110 to $130 in labor/parts.

If you want maximum output, ask them to wye wrap
it. This will change the characteristics of the output.
At idle speed it should put out about 30 amp, and the
output increases in a straight line, vs. the previous
algorithmic curve. At driving speed it should put out
50+ amps. It is hard to get the wire wrapped tightly,
and the rebuilder will need to furnish 70 Amp diodes
(drill out the old ones and custom fit the new ones)
and build a new board for it. 50 to 55 amps is common.
If you replace the rotor you can get another 10 amps or so.
If you want to get fancy, change the size of the pulley on
the shaft and speed up the alternator (not too much or
you will burn out the bearings) and you can bring that
total output closer to 70 amp. Total cost - $250 to $350,
depending on how nice your local alternator shop is.

You mean the same forum that has supported more Pinz owners and supplied and stores more useful information than anywhere else? The same place that 99.9% of people seem to really enjoy and find very useful? Where endless custom work has been shown and shared? You find some tiny, negative aspect of something and blow it up way out of proportion; your logic is about as sound and useful as today's news machine is.

Sounds like maybe you need to take your narrow outlook and go somewhere else. Why bother posting or looking at the forum as you seem to know it all already?

Please submit rebuilt sample alternators for reliability testing / proof of concept.
