Alt Volts ?

Just installed a DC Power 185 Alternator. At idle it shoes 12.2 volts at 2500 rpm still shows 12.2. I was thinking I should see 13.6 - 14.0 volts at 2500 rpm. What volts are you all getting?

I get 14 volts at idle, after the glow plugs turn off. That's also with nothing on. With the parking lights on, it's about 13.7 volts.

12.2 isnt good.. Im getting 14.4 on startup and 13.8 or higher running warm. You want to be in the 13s to be safe.

I venture to guess the voltage regulator is no good.
