Wow, Steve, that's great detailed = info; I was just hoping to get the total. I was expecting the injectors to draw more than the coils, but with all the coils together under 5 amps (and even better for the injectors), then my wiring architecture can get a lot simpler.

Many thanks,

Charlie

Hi Charlie

I think these are in the ball park but not measured under flying conditions only idle.

ENGINE

EC2       = ;            &= nbsp;           &nb= sp;          .3

EM3       = ;            &= nbsp;           &nb= sp;         .5

COILS (D585)              =             5

INJECTORS (Renesis)            =  2

FUEL PRESSURE PUMP  x 1 =  8.4

FUEL TRANSFER PUMP x 1 =  1.6

O2 = SENSOR           &n= bsp;           &nbs= p;     0.6       =

Total = Engine           &n= bsp;           &nbs= p;    18.4
