2001 dodge dakota sport electrical problem

The PCM is on the passenger side inner fender. No, the voltage regulator is not in the alternator, it's in the PCM. If it fails, you have to replace the PCM.
P0622 - generator field not switching properly.
P0300 - multiple cylinder misfire.
Pull the alternator and get it bench tested. That'll at least give you an idea. Most alternators last about 125k or so.
I strongly suggest you treat the P0300 as an emergency. Continued operation can damage the catalyst. How are the plugs?

I failed to mention that I have the 4.7 Liter 2003 dakota. I just replaced the alternator with a remanufactured one 2 months ago when my headlights slowly faded to darkness on my ride home from work. The new alternator fixed that problem now I have P0622 2 months later. I find it hard to believe the voltage regulator is in the PCM because the post coming off the alternator and the plus side of the battery meet on a post on the driver side Power distribution / relay panel. as far as the P0300 I will change plugs right away - thanks.

Where can I buy a PCM for a 2WD 2003 4.7L, 5speed manual , if I need it? Alternator output IS fluctuating I'll have AdvanceAutoParts test it where I bought it in February. Any chance PCM is affecting P0300 multicylinder misfire? I already replaced plugs when I got P0308 code (cyl 8 misfire), a few injectors, cyl 8 coil pack, fuel injector cleaner, camshaft sensor and soon to try crankshaft sensor.
