Don't belive me? Start your car. Listen REAL close.
Turn all accessories off. Then turn on your headlights. You WILL hear the alternator load up and drag the engine down slightly.

Go put your vehicle on a dyno sometime. Run a dyno run with your headlights and all your electrical accessories running. Then make a run without. You WILL see a HP decrease when you run with accessories on.

Yup.
This is why you set idle speed and timing with the a/c, headlights, etc. turned off. On my 88, I have to act quickly and work between cycles of the electric fan...the rpm will drop by about 50 when it's on at idle.

I'll try to be more specific from now on... no need to kick the dead horse... I'll just sit here quietly in my corner feverishly biting my tongue for now on

Sorry for kicking the proverbial dead horse again, Peter...I replied before realizing there was another page of posts. I reserve the right to pull a stupid newbie maneuver from time to time. <img src="/forums/images/graemlins/smile.gif" alt="" />
Hey, what engine can I swap...
