Do you have a brand name and /or model number for the actuator? Is it a jack or a motor? your signature line gives me a some ideas, but as I try to reasearch some of my old sources, I come up with conflicting answers.
do you have the cover off the connections on the motor? look for obvious damage or rust / corrosion at the jack terminals, note which wire are connected where on the terminal strip. If the connections are ok then I would suspect the cable is damaged between the receiver and the jack, or the sensor itself has given out. If it is a 14 year old reed switch in the sensor - - - the chances of it failing are over 80%. If it is optical, 14 years of dust and insect collecting may be a problem. Hope that gives more ideas / insight - at least for someone who has done BUD work since I have. POP
The actuator is a Super Jack (Venture-V81074-319827). There does not appear to be any rust when the cover is off. The Jack arm appears to be extended more than usual. When I look inside I see a red, black and a white wire (Small), but the white wire appears to be not connected or maybe grounded in the back where I can't see it.
Do you know exactly where the wires go on this model. I tried to check the wires and when I replaced them the label I put on is faded so I don't know where they go.
if its over extended then it will move just a click or two before erroring out. if it is over extended then you would need to help the dish back west usually you can achive this with one person at the dish lifting on the east side and another person on the inside telling the dish mover to go west ( this might take several tries).
i suspect with all the reading i've done, is only two small wires should be connected. red should be sensor (pulse) and black should be ground
those sensors are what i'm working on now some you can find for a couple of dollars each others you can find for close to $30 each i bought a set of insides to the sensor ( the guts) 10 for $6.50 hoping to repair a couple of bad ones and to test with ... so once you know how to install them yourself its a lot cheaper than having a repairman out to fix the problem....
