Alternator wiring issues
Looks like we have some non-standard color choices.
Lets start with the easy to identify.
Ground stud on alternator housing. Heavy Red wire to fender.
The use of a supplementary ground is usually not needed.
However, its possible this is the only ground between the engine and body. Stock is usually a block wire from back engine ot firewall.
Additionally if the battery has been moved to the trunk, additional grounding would be helpful. Bassically it can't hurt. Only danger is that it has red insulation and people assume red are hot wires.
Field terminals. Each one is attached to a carbon brush to contacts the copper rings of the rotor. You can see the one ring and the white insulation in the photo.
When electricity flows through the windings of the rotor an electromagnetic field is created. Field is shorthand for electromagnetic field.
'72 would use a voltage regulator with a triangular plug.
This \/ appears to be an emmissions related switch that was picking up outside air temperature coming through the cowl.
I don't think its related to anything with the way the car is now setup.
Output stud.
This should have a heavy wire, 12 or 10 gage, going to through the firewall to the main splice. At least that would be the original setup.
No problem.
