I fixed the tranny issue on my ElCo just to have another issue pop up. My car started making a weird noise as if the starter was initiallizing as I was driving.
So I got home and turned the ignition off, but my car kept running. The wires that connect from the battery to the alternator got extremely hot and started melting the rubber. The ground wire on the battery did the same.
So I disconnected the positive cable to the battery and it shut off. I disconnected the alternator all together to see if that was the cause. Turns out it wasn't. I checked and replaced the ignition switch and that wasn't it either. The. I checked the fuse for the ignition, and it was burnt out. I put a new one but still had the same result.
My car is revving with the alternator completely disconnected.
I'm pretty much fed up. I fix one thing and another thing always pops up.
I would really appreciate some help.

need update
was it the vent tube that was plugged up ??
or just overfilled ?? or ??
.
problems, on a 30-40 yr old car..
think of it as an adventure,
new ride, unknown repairs by the previous owner
who sometimes don't have a clue, and picks the path of least resistance,
or just lazy, or too much help from a "car guy, want-a-be" ..
you see where im going... check everything, 2 times..
.
new problem
sometimes when the trans is dropped, you can pinch
all or some the main power, charge, crank, and run wires ..
they all run across behind the motor and into the cab,
to/from the starter, alternator, battery connection on the starter..
or sometimes they just fall down and hit the hot exhaust on the
pass side around the starter, if there not bundled-up and tied..
.
if its a short, it could be anywhere..
there should be Fusible Links like slow-blow fuse/wires at the starter,
that's where i'd start, and work my way to the alternator, and
firewall connector under the brake master cylinder..
check the main positive and negative cables too..
theres some between the motor and the AC box that's a problem on Gbodys too..
.
heres some wire diagrams

Ok I'll check them.
The tranny problem was due to the radiator. It was full of rusty mud. Flushed it out, cleaned the overflow tank out, and no problems since.

check it out and let us know if you have any more questions..
it does sound like the Purple Crank wire from the switch to the
starter solenoid is shorted to one of the Red main power wires,,
that happens kinda often in the metal tube by the starter..
that would engage the starter and could back feed the distributor
thru the switch..

So that problem was solved. Open wires and arching.
But another one has popped up. Just my luck. The alternator isn't charging the battery. Put a new alternator and starter in. Still the same issue.
Took the terminals off and car dies. I'm stuck. Don't know what it is. This car is kicking my ass.

see if you have power on the small brown wire in the 2wire connector on the alternator
with the key on.. that's the power that turns on the alt..
if not,, check the gauge fuse.. anything else not working on the dash ??
do you have a Alt/Gen light [check it too] or a gauge ??
and
there should be battery voltage on the 2 bigger red wires all the time, with key off..

sometimes when the fusible link blows, it wont burn thru the insulation..
if you pull on them and they stretch, its probly burnt..
checking for power on the red wires will usually tell too..
.
.
checking to see if the alt is charging by pulling a battery terminal was
kinda sorta ok back in the old days,
but with a computer/ECM/electronics its not a good idea.. use a volt meter..
12.6v-12.8v on a good hot battery,, 13.8v -14.2 running/charging..
