I have an SD-8 installed as a backup alternator on my IO-540. I do not have a shunt installed on it's output so I am unable to see an Amperage draw on it when it is activated (and primary alternator is disabled). But when I load shed down my system down to about 3As, increase RPMs to 1800 the voltage goes from 14.7 (on primary alternator) down to 13.2V when on the SD-8.
Is this the expected voltage for the SD-8 when operating or is it possible the SD-8 isn't properly outputting to the main bus?
