[DML] Re: Cooling fans - current draw

Your really need to have the engine running or be powering with a power supply.  You also should be using 14 AWG wire connected to the meter.  You will find without doing these things your readings will be 2 or 3 amps lower.  Also measuring fans not mounted (blocked) by the radiator will increase the current.  My OEM fans not mounted will be greater than 15 amps a 13.5 volts.  I wish I checked the current before removing them.
