96 Safari Van wrapped speedo when battery was dead, now what?

[Duane]

I was cranking over the father in laws van that we are trying to sell for him the other day and the battery is run down. Well it cranked slowly and then almost like it spun backwards or something and at any rate the speedometer wrapped clockwise and now sits under the zero pin. Is there anything I can do to fix this thing now?
thanks
