Ford: 66 Mustang Electrical Help???

it is obvious he does not know what he is doing. first thing, the starter will
show resistence. if it does not ,it is no good. the first thing he should get
is a service manual and then a wiring diagram.
there is a troubleshooting section in the manual that will solve 99% of all
problems

That spark when putting on the negative cable means that somewhere something
is drawing a lot of current. It sounds like a major ground. I would look at
the voltmeter and it's wiring first.

Every day is a good day- it's just that some are better than others.

If the battery cable arcs when he hooks the battery up something is
drawing current, he needs to figure out what that is or he will run the
battery down every time he leaves it sit. With an older car there
should be zero current draw with the key off unless you have the door
open (dome light)

good luck

Car batteries can be charged "backwards" If the battery was completely
drained in storage and he happened to accidentally reverse the polarity when
he charged the battery... Pos may now be physical ground.

Thanks to all for the input you provided. It turns out it was the voltage
regulator. The reason he didn't replace it with the other things was because
he was told that when he bought the car it had just been replaced. Could
have just been a bad one. Everything seems to be working for now. We will
see how the next few days go and see if there is anything else wrong with
the electrical system.

You partially solved your problem but still need to attend to the battery.

Typical FoMoCo generator-regulator ailment due to a bad generator regulator.
Those regulators were prone to go bad and had three stage electro-mechanical
relays in design.

DO NOT operate the vehicle without either replacing the battery or recover
it by discharging it and correct recharging.

The battery if it is not old may be recovered by completely discharging it
SLOWLY by leaving the headlights on until the lights are no longer
illuminated.

Then recharge the battery SLOWLY connected with correct polarity to a
constant current charger. Most constant current chargers have a heavy
transformer. Constant voltage chargers have a light weight transformer and
normally sold today at many discount stores.

I had a '66 Mustang years ago (289?) and it used to "eat" regulators. I
think this was the main electrical problem with these cars. Also, I got
quite good at changing water pumps :-) might a well tell your brother to be
prepared for this!

If it's a 289, with a manual trans, then also watch your rearend.. my
father had a 66 289, and put about 5 rear ends in it.. the 289 has tons of
torque and would shear the rearend gears.. he also broke a universal on
it.. broke it clear in half..

BUT.. that car would lift the front end a few inches off the ground when
he'd pop the clutch.
