Finally got the time (and weather) to dive into the cruise control problem. Did all the tests in the FAQ's but still no cruise. I ended up hot wiring the vac pump right to battery and ahha. No motor run. Ohmed it out and it had 10 OHMS resistance which is spec. Hmmm, motor was getting power but would not run. Motor was not open circuited or shorted. 10 OHM was spec. SO i rip it out and remove the black cap over the motor. It was totally full of white corrosion powder. Filled. I wirebrush it all off. blow it all out. lubed the upper bearing put some visegrips on the armature end and give it a little twist and plop it free's up. I then take the front vac end oblong cap off and clean it all out. Get all the corrosion out and hot wire it again. I stuck my cheap vac guage on it. 2 inches running free and 22 inches when i wire in the governor. Sweet. Put it all back together and install it. Yay cruise works great.
