Okay i found a cool way to measure current draw. You get a 1 Ohm resistor 10 watts will work but a 250 or 1000 watts would work better if you want to leave the meter connected when you run the car. You use a volt meter (not amp) and measure current drop across the resistor. the resistor is inline with the neg battery cable and the volt meter goes on either side of the resistor. Scotty Kilmer on Youtube uses this method with great success.
