1969,144. B20. Alternator problem.I thought at first when the engine barely turned over on starting was due to an old battery. Replacing the battery with a new one made no difference to the slow turn over after a sixty km trip.I suspect the alternator or regulator. (it was a new battery fitted)
First of all how do I check the alternator or regulator for functionality?
Secondly should the alternator or regulator be faulty can they be repaired?
If not repairable has anyone used a different alternator from a different vehicle?
Could something else be draining the battery when standing over night?
The red charging light does go out after starting. Also new battery.

After trying to charge it without much success I am beginning to suspect a faulty new battery. It hasn't seemed to receive a full charge after an overnight charge on my CTEC. Another battery charges fully on same battery charger.
Question. How I test the new battery. I have a multimeter?
