ICE loads

[basjoos]

When I got home from a recent trip, I tried adding various electrical loads to the engine while monitoring the pulse width displayed on the SuperMID. Below are the results.

Warm idle with nothing turned on........2.3 to 2.4
Parking lights on..............................2.4
parking and headlights on..................2.6 (high or low beam)
Brakes on.......................................2.4
Fan on lowest speed (level 1)............2.4
Fan on next higher speed (level 2)......2.4
Fan on level 3.................................2.4 to 2.5
Fan at max speed (level 4)................2.5
A/C and fan at level 2......................3.6
A/C and fan at level 4......................3.7
ICE cooling fan on...........................2.4
Radio on low...................................2.3

I also monitored the pulse width for the 1st minute of idle when starting a cold engine at 55F ambient temp.
Start idle.........4.2
After 30 sec.....2.9
After 1 min.......2.6
