Well, Bob's pushbutton actuator is finished and back on it's way to GA. This one presented new challenges,as many do. Someone has been in it before, and had problems with water making its way into the unit. Their solution was to drill a series of drain holes rather than seal the unit!
The gearing had been taken apart and put back together incorrectly, not life-threatening, but incorrect. Many of the fingers had been distempered, and were not making contact with the contact segment. Look at picture #8--the grommet for one of the motor wires was missing--Well, I now replace those! There was insulation melted from the wires going to the finger-plates. I potted the exposed section of wire in rubber, that is visable on photo #16. The wire that was exposed on the top portion of the rubber sealing block could be a big problem, so I pot those in new rubber compound, as illustrated in phot #16. I cleaned his connector terminals, which were going green. the captions on the other photos describe everything else. I'll be posting videos of this unit on youtube, maybe tonight, and will give y'all the links when I do.
