After several recent months of cleaning, repairing and replacing various and assorted components we successfully energized our 48 volt battery pack. With just one battery pack we are able to use Speeds 1 through 3. Speeds 4 and 5 which require two battery packs in series for 84 volts will not be used at this time. We have placed a restrictor block on the controller sprocket to block those speeds for now.
We saw a bit of arcing in the controller even though we used the conductive grease as suggested by the guys at Rev's museum. A check of the fingers showed that some of them were not seating on the contacts hard enough. We disassembled them and bent the finger blades by hand to exert more pressure. This greatly reduced the arcing.
So everything worked great in the forward speeds. However, reverse was not possible because the speed controller mast is improperly adjusted. Therefore, we were not making proper contact in the reverse switch. This turns out to be a non-trivial adjustment involving relocating the controller mast mounting bracket and other things which we haven't quite figured out yet.
So we're going Forward for now...will Reverse some time later.
