When reinstalling the alternator on our ‘66 Coronet I “ assumed “ the black wire was a ground . There were three wires . A dark blue that I plugged into the “ field “ spade connector. The thick red ten gauge went from the threaded post directly to the battery .
In hindsight I should have connected the black wire here , true ?
When I connected the battery negative terminal the smell of wiring burning told me indeed I had made a mistake .
I believe this fusible link is what sacrificed itself by shorting out . Any help in locating a replacement would be greatly appreciated. Thank you

It appears someone has bypassed the OEM black (original alternator output) with the red wire. The black runs through the bulk head connector (P cavity) and feeds the ammeter and several other circuits at a large splice behind the dash. If you do not have a FSM you should purchase one.

You can get a new fusible link from Jamie at Mega Parts in Lacrosse, Wisconsin. May be time to think about renewing your old harnesses too.
 
“A Treatise on the Importance of Smoke”

by the Prince of Darkness, Joseph Lucas.

All electrical components and wiring harnesses depend on proper
circuit functioning, which is the transmission of charged ions by
retention of the visible spectral manifestation known as "smoke".
Smoke is the thing that makes electrical circuits work. Don't be
fooled by scientists and engineers talking about excited electrons
and the like. Smoke is the key to all things electrical.

We know this to be true because every time one lets the smoke out of
an electrical circuit, it stops working. This can be verified
repeatedly through empirical testing. For example, if one places a
large copper bar across the terminals of a battery, prodigious
quantities of smoke are liberated and the battery shortly ceases to
function. In addition, if one observes smoke escaping from an
electrical component such as a Lucas voltage regulator, it will also
be observed that the component no longer functions.

The logic is elementary and inescapable! The function of the wiring
harness is to conduct the smoke from one device to another. When the
wiring harness springs a leak and lets all the smoke out of the
system, nothing works right afterward.

Starter motors were considered unsuitable for British motorcycles for
some time largely because they regularly released large quantities of
smoke from the electrical system.

It has been reported that Lucas electrical components are possibly
more prone to electrical leakage than their Bosch, Japanese or
American counterparts. Experts point out that this is because Lucas
is British, and all things British leak. British engines leak oil,
British shock absorbers, hydraulic forks, and disk brake systems leak
fluid, British tires leak air and British Intelligence leaks national
defense secrets.

Therefore, it follows that British electrical systems must leak
smoke. Once again, the logic is clear and inescapable.

Sometimes you may miss the component releasing the smoke that makes
your electrical system function correctly, but if you sniff around
you can often find the faulty component by the undeniable and
telltale smoke smell. Sometimes this is a better indicator than
standard electrical tests performed with a volt-ohm meter.

In conclusion, the basic concept of transmission of electrical energy
in the form of smoke provides a clear and logical explanation of the
mysteries of electrical components and why they fail.

"A gentleman does not motor about after dark."
- Joseph Lucas, 1842 - 1903

I learned a long time ago that once you let the "Factory Smoke" out of
any electrical device, it is next to impossible to replenish.

I concur wholeheartedly. The time and money spent is well worth it. Not only for the aggravation of breakdowns, but moreso for a possible catastrophic event like a fire.
 
Thank you. People usually beat me up and say it's a waste of money replacing with new harnesses, when you can replace just one wire. This usually happens over on FABO. I have had 2 cars with totally hacked harnesses, it's not a waste of money for my piece of mind.
