The $5 harborfreight multimeters are within a 1/10 of a volt or so compared to the flukes, and I have a $300 fluke, I use the cheap HF meter more, it's close enough for what most will use it for working on their own cars.
Anyways I'm wondering how you know the car charges for a few mins and stops? Usually the PCM will tell the alt to charge, or not charge. Not just random charge and stop, or an alt will charge or not charge, not just do it sometimes.
