65 amps? I was thinking the oem alternator of that era only put out 45
amps, but my memory can always be bad...
One thing you might check (though this probably is not the problem) are
the grounds for your stereo and the voltage regulator. If they aren't
good grounds, a good stereo can put too much drain on the system even
with a higher output alternator.
If you do wind up with a higher output alternator, check the amperage it
is putting out at idle. Sometimes they actually put out less amperage at
idle than the oem alternator does!

the replacement I got was made for Cop cars, puts out more at idle, I think
they called it a Ford generation 3, This guy at alternator place says they
got fleets of Ford trucks in from delivery companies they upgraded the
alternators, and Ford paid for it.

That's because Ford writes it off to their advertising budget which
IIRC is deductible off the corporate gross under the tax system. Back
when California Highway Patrol got the 5.0s, they cost the state
$4,000.00 per car and Ford got a LOT of advetising/PR mileage out of
the CHP using them.

This is an original A Code V8 4bbl and is rated for65 (really more
like 62 amps, and probably less at idle).
I have a new light switch to put in it, which I'll do before a new
alt. I learned a long time ago with a cooling system problem to start
at the cheapest repair and work up rather than the most expensive and
find out a $2 part would have done the job. :0)
My dad came by yesterday and over dinner I picked his brain. His whole
life has revolved around electrical and electronic. He said it sounds
more like a bad ground. Knew I kept him around for something! LOL

87-93 LX alt was 45 or 50 amp and GT 65. My LX is the one with the
"25 Years" tag so it was one of a bunch that the dealer ordered loaded.
It has all the options that you could get on them that year so it also
had the 65 amp alt.

I just got an '89 5.0 LX with the 25-year pony on the side, and it is in
the shop now having a bunch of the little niggling things taken care of.
Should I look for a new alternator, or just wait til the existing one
dies?
