Is the cooling fan coming on as thhhhhhe ammeter drops to zero and goes negative?

I have seen several cars with underdrive pulleys which circulates the water more slowly and doesn't turn the alternator fast enough to keep up with cooling fan and lites.

Many will drop to 9 or 10 volts when the fan comes on with an 80 amp alternator with underdrive pulleys.
