It trips before the delta contactor pull in
Who is the he you ralk of, was / is he an electrician? 10 to 1 he has screwed up the connections if he did refit it
 
Check the winding connections. Could be trying to rotate in opposite direction after star contactor opens and delta closes. Seen this before. Check winding pairs with ohm meter.
Don't think that could cause the problem.
