Funny, but then how do I measure the amps then? I guess I could use one of those fancy formulas to calculate the amps but its easier to change fuses when I pop them. LOL Sweet generator by the way. I don't think you need the 10 gauge wire because thats probably whats already in there. at 30+amps measured its plenty to charge a battery. I would run 10 gauge from the bumper back to the trailer and have an isolator on that.
If you know the voltage(easy) and check the ohms(easy) you know the amps. voltage/ohms = amps. Ohms will probably be below 1.
Watts are amps x volts fyi. Easy to check how many amps a light will pull. If you buy a 50 watt light and you know with the car running you have 13.4 volts - 50/13.4 = 3.74amps. If the car was off and you only had 12 volts it would be more amperage 50/12 = 4.1amps.
With my 4, 55 watt (wussy) offroad lights on my rack the amperage is (not including resistance from the length of 10gauge wire) (55w/13.4v)x4 = 16.41 with the engine on and (55w/12v)x4 = 18.33 with the engine off.
