Re: My stupid Jeep question of the day
GM ones have a 3rd 'excite' wire to turn on the alternator.
It is a thin (usually brown) solid core wire that tags the coil power
wire on the 12 volt side of the coil's ballast resistor or ballast wire
in the CJ's. On the CJ's it tags the harness right to the passenger
side of the brake booster.
When I turn my current alternator pulley, did it today, the crank turns
too.
I have a really swingy alternator volt gauge right now and have a
voltage drop from the battery center post to the alternator red wire.
It also drops at the solenoid bolt and on the red wire's O ring and the
red wire where it goes into the cable clamp on the battery. If I put
the meter on the positive cable clamp, I have no drop, so the connection
between the clamp and the main wire is toast which kills my battery
pretty fast.
I just keep on charging up my battery because I am not in good enough
physical shape right now to take the sucker apart and clean it. I am in
recovery from a nasty car accident I was a passenger in. T-bone hit on
the passenger door where I was sitting. Physiotherapy says I am lucky I
have a 19.5" neck or it likely would have been broken and I have had a
stroke from my head hitting the door post. I am not allowed to turn
wrenches, or better said I am not allowed to bend in the right ways to
turn wrenches....
If you use the meter on 20 volts, check the two battery posts with the
engine running, then move the meter probes to the clamps one at a time
and see if the volts drop.
Then have the red meter probe on the positive and go to the alternator
case, the volts must be 'exactly' the same.
Then hold the black meter probe on the neg post and go to the red bolt
on the alternator, then back to the solenoid bolt, then to the solenoid
wire cable loop, then to the red wire clamp on the battery.
If the voltage drops even 0.01 volts, the connection is bad.

Re: My stupid Jeep question of the day
I think this is your problem. Per my wiring diagram for '76, the green wire
runs from the field terminal to terminal 44 on the regulator. If this isn't
hooked up the alternator gets no "exciter" current and basically doesn't
generate any juice. The regulator should have a yellow wire at terminal 40,
which is spliced in the harness to the big red "bat+" wire off the
alternator, and a black wire at terminal 16 also spliced in the harness to
the red w/trace wire off the ign switch.
Fix the green wire and I'll bet the thing works.

runs from the field terminal to terminal 44 on the regulator. If this isn't
hooked up the alternator gets no "exciter" current and basically doesn't
generate any juice. The regulator should have a yellow wire at terminal 40,
which is spliced in the harness to the big red "bat+" wire off the
alternator, and a black wire at terminal 16 also spliced in the harness to
the red w/trace wire off the ign switch.
Fix the green wire and I'll bet the thing works.

Re: My stupid Jeep question of the day
I think this is your problem. Per my wiring diagram for '76, the green wire
runs from the field terminal to terminal 44 on the regulator. If this isn't
hooked up the alternator gets no "exciter" current and basically doesn't
generate any juice. The regulator should have a yellow wire at terminal 40,
which is spliced in the harness to the big red "bat+" wire off the
alternator, and a black wire at terminal 16 also spliced in the harness to
the red w/trace wire off the ign switch.

Re: My stupid Jeep question of the day
Hi Mike,
Really sorry to hear of your accident. Get well friend.
Coincidentally, I've got the same thing happening with the sentra. I know
it's sort of off topic, but along the same line. It left my wife walkin'
the other day. When I got to where the car was it was dead dead. I pulled
the battery and put it on my charger until topped off. Went to the car
started it, got it home. Checked my connections with and without engine
running. I know this is not the best thing to do, but I disconnected the
negative battery terminal, with the engine on, and it died. Mind you, this
is the second alternator to crap in this vehicle. This one only lasted 8
months! Strange? The odd thing this time was that red idiot light on the
dash was not lit up like it was when the original one died. Could this be
because the battery was nearly full? Only had to drive it about a mile and
half. My wife couldn't remember or didn't notice a red light on.
Fortunately, this has a lifetime warrantee and Auto Zone handed over a
replacement without question. Pretty impressed. They had all my warrantee
info in their computer system. Didn't need the receipt even though I had it
with me.

Really sorry to hear of your accident. Get well friend.
Coincidentally, I've got the same thing happening with the sentra. I know
it's sort of off topic, but along the same line. It left my wife walkin'
the other day. When I got to where the car was it was dead dead. I pulled
the battery and put it on my charger until topped off. Went to the car
started it, got it home. Checked my connections with and without engine
running. I know this is not the best thing to do, but I disconnected the
negative battery terminal, with the engine on, and it died. Mind you, this
is the second alternator to crap in this vehicle. This one only lasted 8
months! Strange? The odd thing this time was that red idiot light on the
dash was not lit up like it was when the original one died. Could this be
because the battery was nearly full? Only had to drive it about a mile and
half. My wife couldn't remember or didn't notice a red light on.
Fortunately, this has a lifetime warrantee and Auto Zone handed over a
replacement without question. Pretty impressed. They had all my warrantee
info in their computer system. Didn't need the receipt even though I had it
with me.
