Most likely 12 volts if it is on a car. Some boats use 24 volts, or in the case of my boat 32 volts.
It should put of 13.5 to 15.5 volts. The alternator is an 80 amp alternator.
13.5 - 14.5
It is a 12 volt alternator. I think what you are looking for is how many amps is it. Most of them are 105 amp alternators.
140 amp
This will still only produce 12 volts. It will produce 1200 watts. watts is the result of Volts times Amps.
Check your RPO codes. If it has K60 then you have a 100 amp alternator.
Rated output 135 amp, load test output 94 amp - this is assuming stock alternator, replacement alternators vary as some rebuilders mix and match parts...
Watts or Amps? Amps would be the alternator, don't know where you would find watts. Volts X Amps = Watts, for example 12 Volts X 55 Amp Alternator = 660 Watts
95 amp ( 115 amp with trailer tow , camper , or snow plow package ) according to motorcraft . com ( no spaces )
It will vary depending on what demand you are placing on it such as heater, brake lights and so on but it should put out about 14 volts pretty consistently until fully charged and then about 13.
watts = volts x amps, example-2 watts=2 volts x 1 amp, example- 2 watts=120 volts x .60 amp.
Your stock alt. will work just fine.
