I picked up a used c50 last year, it did not come with an owners manual or service manual. I need to get under the seat to the electrical harness - does the seat come off? and what is the trick?

 

to get under the seat you need to remove the bolt holding the rear seat on then slide the rear seat back off of its front hook(just pull it backwards) then under that seat you will see the two bolts that hold down the drivers seat take those two out and you can lift the seat off to access the battery and some of your wires.
