double check that dataplate, check to see if its been slapped over another dataplate, that model number i bet is not accurate.

this a 3 wheel sitdown electric i presume?
check the frame on the left side floorplate just in front of the battery plate, the serial number will be stamped there as well beginning with the model number then a dash (-) followed by the serial.
The contactors are in a panel on the left side of the truck near the back end if i'm thinking of the right model.
go in there and make sure there are no welded contactors (stuck closed)

Hope this helps, i dont have any diagrams but i am currently working on a toyota at a customer that is almost the same model (2FBCE15) but the accurate model number turned out to be a 2FBC15 when i looked behind the dataplate on the origional one and compared it to what was stamped on the frame too. ;o)
