[C320-list] ignition switch and Alternator

[jim brown]

I know this is about old British cars but it has helped me (on an old British car) test an alternator using just a volt meter.  View to the end and it explains how to test for a failed diode-like when you go through OFF on the battery switch. Hope it helps

My alternator does not appear to be charging the batteries. I put the volt
meter on the terminals on the alternator and 0 volts (positive and negative
screws). 

 

I pulled the alternator out and off to the repair shop. Oscar tested the
alternator and said it is fine, producing 14.5 volts.

 

How do you test the alternator with the volt meter? 

 

What would prevent the alternator from charging the batteries?

 

Could it be the ignition switch?

 

Thanks for your help
