Zero. There's no wattage in a 12 volt alternator.


W=A x V So watts equals amps times volts. How many watts do you need? Alternators are rated in amps, my book shows 3 different alternators, so more information is needed ie engine, optional equipment, etc.

I do not know the WATTAGE, but it has about 50,000 ohms so just be careful with it.
