Thx!
quirks of the car: have to jiggle the key to get the heater blower to fire up and I pulled the trunk light as a precaution...
Is this an SD made from 85 or older?

"Alternator tested at low Voltage"; was that an on the Car Test or was the Alternator removed and taken for a Free Test at an Auto Parts Place?

If the Test was done on the Car the Charged State of the Battery and the Wiring could influance the test.

When you first turn the Key all of your warning Lights including the Charging Light should go on. That tests to see if the Bulbs in the Warning Lights are OK.
If the Charging Lignt does not light up during this test the Bulb may be no good. Without that Bulb in the Circuit to excite charging your Alternator is not going to charge properly.

And, if your Iginition Switch is having issues that could als effect the operation of the Alternator.
Measure the Battery Voltage after the Car has sat awhile and not when it is running for the next stuff.
If your Alternator has the Connector/Plug with 3 Slots. The 2 Large Slots will have Battery Voltage all of the Time.
The single Smaller Slot connects to the Charging Light and the Ignition Switch. When you turn your Inition Switch on without cranking the Starter you should get slightly less than the Battery Voltage.
