Did they ever work right? If not, they are almost certainly
wired wrong.

Besides the big post on the alt that goes to the battery,
the two on the plug on the side of the alt are:

* dash ALT light + 'turn alternator on now'

* sense wire 'alt measures actual battery voltage'

The ALT light is wired


switched ignition --> ALT light --> alternator terminal

When the ignition is turned on, current runs through the ALT
light (idiot light) into the guts of the alt and into the field
to start the alternator. No lamp, or severely wrong lamp (note1)
alt wont start. 


The sense wire measures the battery voltage and compensates
for voltage drop in the wiring etc so that the alt puts 14.4V
on the battery regardless.








NOTE1: I have an LED lamp replacement in my dash; it doesn't draw
enoug current to start the alt below 1500 rpm, but it reliably
does once I've revved it. I'm goin to fix it "real soon now" :-)

Jack from personal experience don't waste your time and money on one of
those gas tank sealer kits. Have it professionally repaired. I put the
newer 21 gallon tank in both my 74 Hornets. It is still available new as
it was also in the Eagle wagon's and 4 door sedan's. It was the same
size but just deeper so with new gas tank straps it was almost a bolt in
with only minor mods needed to hook up the fuel lines and vent line to
the roll over valve. A new fuel tank sending ring and gasket ("O" Ring)
is also available over the counter too. The sending unit itself I had to
get a NOS one from Kennedy American. On the rear noise I think all the
AMC rears of the era were set up loose and made noise even when new. If
you are gong to change the pinion bearings also change the ring gear
carrier bearings and wheel bearings.

Progress has been slow on the tank project, but at least I am inside out
of the horrible heat and humidity in the A/C working on it. I started
with a billet radiator over flow tank. I modified the filler cap neck
ramps so the cap would open easily without having to push down with
excessive force to clear the locks. I also removed the overflow gasket
from the cap so the tank is now vented. I am also in the process of
removing 1/32" of material from the top of the billet cap to remove the
mfg's machined in logo. In order to get the socket in through the filler
neck to install the nut for the pump I had to grind the inside of the
filler neck for clearance. There was plenty of material but not where it
was welded to the tank. The neck separated from the tank. I used JB Weld
and re-installed the neck. I roughed up the mating surfaces and now that
it is dry it is like it was welded on again. Love that JB Weld. Next I
have to open up the hole in the bottom of the tank so the pump will fit.
Aluminum is a pain to work with as it filles up your grinding stones and
rotary files surfaces. I have to make a trip to Sears this morning for
some more supplies for my Dremil. Once all the mods to the tank and cap
are done I will have to polish it out. It may seem like an excessive
amount or work but that old crappy looking plastic tank looked horrible
next to the polished billet radiator over flow tank. It also wasent
cheap either as it was 146$ for the tank including shipping from Jeggs.
