AC on, in gear, 650 rpm, 14.30v
Engine warm, choke off:
AC off, 750 rpm, 14.56v
AC on, 600 rpm, 13.23v
AC on, in gear, 550 rpm, 12.40v
Voltage reading is steady with AC off, fluctuates a few tenths with AC on.
Headlamps dim slightly (nothing flickers) at idle when AC is turned on. Frankly, at this point I'm not concerned about it.
Side note: The LED bulb in my dome lamp chose this exact moment to flicker and then die. I'm thinking just great, that's what I need is more electrical problems. Turns out it was a failed bulb, and I had one (standard, not LED) on hand.  |
You should idle up with the motor warm no choke on to around 650 in gear maybe 600 just depends on your self really. With the choke on it's going to idle pretty high which is what it's for to warm it up in the winter time.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!
LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
