injector cooling fan

i have a few questions about the injector cooling fan. its located on the right fender next to vacuum resevoir. does anybody know how much voltage it should get? and would that be after engine warms up? i'm getting .5 volts with engine warmed and 0 ohms between terminals on fan motor. is there a resistance spec.

At some point, the after-run fan should have 12v to make it run. I haven't checked to see if the fan runs before turning off the engine, but it should run after turning off the ignition on a warm engine.
If someone could tell us where the "feed" actually comes from for the fan when it says the engine is up to temp, it would help. The under-dash fuse ('89 F150) for the After-Run Blower is #16. It also feeds the horn. So if the horn works then the fuse for the blower is OK.
If anyone has any wisdom for everything important about the After-Run Blower, please share the details. :-)
