Having thought my alternator was not working, I went to great lengths to remove and test it only to find it was producing 14.2 volts. Wiring from the alternator to the battery was the culprit.
My question is that on normal driving I notice the needle in the charge area but if I turn on the “heating” fans ha. the wipers and the headlights, the gauge will definitely make a jump to a point that is just barely in the charge section. I can only imagine that the original style generators were taxed way beyond their capabilities especially with the batteries from that era. There was mention in the archives of the rear window demister always being on in the earlier models with this option and mention of a 50 amp draw. That does not sound feasible???
Sometimes the charging will return to the volt meter, but I do worry that I am depleting my battery power.
On this note I bought a new accessory for the car. It is barely bigger than two packs of cigarettes and uses Ion battery power. I am going to test it by running my battery down leaving the lights on and seeing if the hype is true. We did manage to get a scooter/moped with only 5 volts started yesterday which was a challenge with such low voltage on something that had not been started in months. We try to keep the cars on “Battery Tenders” which are wonderful and idiot proof.
Amazon has them for less money.
No affiliation just a happy camper.
Guess the car???
