The car is currently 6 volt and I would like to keep it that way, but the wife want to know if i can put in a/c. So is it possible to run a sanderson comressor off of a 6v to 12v step up device? will the positive ground be a issue? Does it matter?
You'll have a hard time finding an inverter rated for enough current to pull the clutch and fan loads. Most were made for radios and other low current accessories.
Just a thought and I have never seen it done but what if a guy ran two completely separate electrical systems? Keep the 6v to run the car and install a small frame alternator tucked out of the way with a small case 12V battery again tucked out of the way to run the ac and sound system if desired. The battery could be the smallest case car battery available as it wouldn't have to start the car.
I like this idea, A motorcyle or lawn mover battery, just for a kinda buffer to prevent runaway voltage, or maybe not even necessary. Small enough alternator to just handle the fan and a couple amps for the clutch. Maybe also motorcycle? I used to work on buses which had a separate alternator to provide 36 volts to a A/C condensor fan motor. This was a 12 volt vehicle. Ran the alt off the compressor drive, so when the comp engaged, the alt turned and ran the fan. No Battery, cause the load was always on as long as the compressor was running. Frank
i have found one rated for 20 amps. could you wire them in series or paralle? what is the power requirments of a compressor? 20 amps 30amps?
a Vintage Air system comes with a 30 amp circuit breaker that powers the whole system..including the blower fan , controls and power to the magnetic clutch when it is activated by the controls i don't know how many amps the clutch itself needs ,but wire that goes to it is only 16 gauge , so it can't be a big load....but the main power and 30 amp breaker is 12 gauge , so some serious amps must be expected there maybe you should call them and see what they think
