electrical loads, real amp draw on the vx

I finely got around to putting the clamp on amp meter on the battery cable on my vx, then while sitting in the drive way with the engine off, fliped thru and made notes on what the draw off the battery was.

Turning the key "on" but with the engine off (dash lights compleated with self check, door closed, lights off, radio off, fan off) gave a reading of exactly 2 amps, so in my figures I subtracted that number from the total reading.

Heater fan 1st setting 3 Amps
Heater fan 2nd setting 5.4 Amps
Heater fan 3rd setting 8 Amps
Heater fan 4th (highest) setting 11 Amps
all of those numbers were fresh air coming in, switch to recurculation and it added .4 amps to the highest setting due to added air drag.

Brake lights 3.2 amps

After market Radio varried from about .6 up to 4 amps depending on vollume.

Cranking for about 5 seconds gave a starter draw of about 138 amps.
