My alternator was still working but the bearings were going out and making noises so I got another new one. I install it and now the car won`t charge.I took the alternator back to the parts store and they checked it and it was charging. So I buy a new voltage regulator and put it on with the new alternator and it still does`nt charge. I used my 66 wiring diagram and I`m pretty sure its hooked up right.My car was charging just fine till I changed alternators.Where else can there be a problem?Thanks,Tony------------------

Hii had a similar problem...swapped out two alternators and two regulators...still no charging...turns out the dash alt light wasn't going on and telling the alternator to "wake up"...by-passed and wired it directly.... voila...problem was fixed...probably knocked something loose under the dash when i was conntecting my speedo cable...

Try full field the alt by using a jumper from regulator connector (P) connection which is terminal that is by farthest from (G) terminal. Connect (F) terminal which is 2 over from ground terminal to the (P)terminal (The P terminal is a postive battery voltage The (P) terminal may be labeled (B)instead of (P), do this with connector off the regulator. you should see gage come up if it works, and or the motor loads down while idling. Below is the way your connector should be spaced.
(G) (F) (P)

I believe it's positive, ground, and field.

Make sure your belt isn't slipping. It happens more than you think.

Thinking logically, it was charging okay before the change, so as Sportsroof mentioned, check belt, maybe not tight enough or worn. Recheck electrical connections that you actually removed during the change over, maybe just a loose or dirty connection.------------------

Here's how you do it. On the alt there's
a terminal marked "fld". Get or make a
jumper wire with alligator clips on the ends. Clip one on to the "fld" terminal, and
start it up.(unplug the voltage regulator
first) Then touch the other end of your jumper to the "+" terminal of the battery.
The alternator will go max output. If it
does work, that is. The alt. will sing and
the eng. will slow a little if it's charging. If you turn on the Headlights during
the test, when you full field it they will
get real bright if it's charging good.

Jake 11,Will this solve my problem?The other day I ran a jumper wire from the battery post on the alternator to the + on my battery and it was charging like 18 amps.But I know I cant leave the jumper wire hooked up for long cause it will blow my battery.------------------

Did you ck the fuse link's? They are on
the "battery" side of the starter solenoid.
They are fuse wires that melt when you have
an overload. Sound's like you might have
a blown one. If it's putting out 18amp's
with the output wire bypassed, it sounds
like an open circuit, usually caused by the
fuse link's being shorted out. You can get them
at most parts stores, but you'll have to
splice them in yourself.

If you are full fielding the alt by jumpering to battery, you are bypassing the link that feeds the regulator. probably a grn/wht wire at the regulator plug. With the key on you should be have 12 volts at the grn/wht wire at the regulator. If not probab;y a bad fuse link. Another possibly is that the ignition switch is intermittent.------------------

Good point Tom G.
Some other things that are very important
to do are, make sure the battery cables are
clean and tight. Look and find every chassis
ground you can and take it off and clean it
up with sandpaper. On a 30somthing car,you
got to go back to basics. Go to the fuse box
and take the fuses out and clean all the
little fuse holders with some sandpaper.
Ck. the plugs on the ignition switch, and
on the headlight switch for loose/burnt
connections. Clean and repair as needed.
Another problem area is the sockets the
tailight/brake bulbs go into. They get old
and crusty. Hope this helps someone.
