Electric power availability question
With the truck in my sig, I power nothing more than stock with the current electrical system. I dont know what the alternator puts out, or if it even says. What I want to do is add a 12v 250-400 watt pad heater to my veg filter and would like to know if I can do this or if I would need a high output alternator. I wouldn't flip the heater switch until after I have started the vehicle so the glows and all would be off. or shoudl i be looking at amps?
Also, what do I wire the heater to, a battery or the alternator? Is it ok to hook it to one battery only?
