Have an older Dover traction with leveling issues. On an up run, all seems well; speeds reduce and levels into landing with no perceivable issues. However, going down, will overshoot the floor, stop, then, with up contacts pulled in, ease down a bit more, then stop and level in in the up direction. If I give it a bottom call, as it goes into this series of events, it will drop enough to hit the finals, and thereby drop the P contractor. When I jump the finals, U picks, brake picks and car moves down.. To get out of first landing I had to force up, brake and P by hand, allow to slip traction for a moment, then it moves up. This problem began a week or so ago, and while troubleshooting, the MG set let all the magic smoke out, and since I have yet figured out how to catch it and put it back, had to pull gen set and send for rewind. I had my fingers crossed that problem was in generator all along, and that when I got it back problem would have been rectified. Generator was reinstalled today, and obviously, since I am posting here, still having same issue. If anything, I think it actually may have gotten worse, or so it appears anyway. what I have seen goes something like this: car overshoots floor, LD (1&2) drop, and immediately LU (1&2) pick. Since ther is no time between these two events, and the fact that the "10" relay (brake) is in series with U and/or D, it never drops. Car drifts down at about 1.5 fpm, about 4", stops momentarily, drifts another 2 " or so, then levels up. I have been reading these forums all night and tend to believe it is in compounding, but is this something that can or will change over time? As I indicated problem was same thing before generator was sent out. Another possibility, from what I have read is series windings being reverse polarity, but again, issue was there before reinstalled. If either of these appear to be culprit, 1; how do I verify polarity? 2; can somebody post readers digest version of how to check/ set compounding? Just a young gun in the industry, and have not yet had to do this. Thanks tons from Cincinnati!!!!
