I recently replaced my generator with an alternator. Unfortunately, I blew
my cylinder head a week later so I have not done much driving... The
alternator works great-- the lights don't dim at idle anymore!
Are you supplying a field voltage to your alternator? My alternator came
out of a dodge D50 truck. I also salvaged the wiring harness connector. I
wired the large lug on mine straight to the positive terminal on the battery
(Actually the positive lug on the starter solenoid.) I then wired one of
the lugs to the fuse block-- to a fuse that is only powered when the
ignition is on. This provides field voltage so the alternator can start
charging. I left my voltage regualtor intact. Since my alternator setup
completely bypasses it, the regulator just sits there. I have not attempted
to hook up my ignition light yet. For this, I think I would have to mess
with the regulator a little.
They are not terrible powerful alternators-- someday I'm going to figure out
how to install a high-output GM alternator because they are a lot cheaper
and more durable.

Here are some nice easy questions for someone who knows more about
alternators than me (everyone!).
Do Mitsubishi alternators come in two flavors? Clockwise and
counterclockwise rotation? Mine tests out OK at the autoparts store, and
puts out nothing
in the car despite turning off the ignition light. After the engine
is started, the ign. lamp goes out and the voltage at the alternator or
at the battry never gets above 12.2, same reading as the battery alone.
even when reving the engine. Looking at the fan on the alternator, it
will suck air out of the alternator when it turns in the clockwise direction
that is correct for this engine. If the fan is designed to push air into
the
alternator, then this one is meant to turn counterclockwise.
Help!
