Alternator light on

Post by Jefflaserfist »

I have 67 f 100 and my alternator light is on, I have had both the battery and alternator tested and both are good. I've also replaced the voltage regulator and tested to make sure it was charging, but the light is still on. Any advice?

Right now, if you start your truck and put a multimeter accross the battery terminals what voltage do you have?
