help appreciated! I need the wiring diagram for a 4 wheel personal transport vehicle similar to the one sold by hammacher-schlemmer for city transport. This unit appears to be made in china but has no mfgr's ID tag. just sereal numbers on the frame. I uses 2 5000wt drive motors in the wheel hubs, three 12v bats at 36 volts and will back up. Made in 2003 according to key tag? Thanks for any help in pointing me to a source. Hate this reverse engineering.
