Looks like the data logger went south. Here's some raw data:

2130 3516 -4596 -4596 0 0 0 0 1677250
2130 3516 -4596 -4596 0 0 0 0 1677500
2130 3501 -4596 -4596 0 0 0 0 1677750

First column is voltage * 100 or 21.3v (should be 34v or better)
Second column is current * 100 or 35A which we saw in the graph.
