Default Re: Project Crossfire - a Rotrex Supercharged Limited!

Well, the little resistor didn't work out to fool the sc clutch as I keep getting an SC malfunction error. So I dug around WIS and found a note that the sc clutch draws 47 watts. Now if I have this right, at 12v this is 3.9 amps at 12v and I need a 3 ohm, 50 watt resistor.

I don't have quick access to one so I'm going to build one with what I can pickup at Fry's.

=

12v / 6.8 ohm = 1.76 amps x2 = 3.52 amps
12v x 1.76 = 21.12 watts so (2) 25 watt - 6.8 ohm resistors should be great

Plus

12v / 30 ohm = .4 amps
12v x .4 = 4.8 watts so (1) 25 watt - 30 ohm resistor

Total draw = 47 watts

I hope that's right as I'm going to solder her up and wire her in soon!
