Assuming this is single phase.
If you cannot locate a wiring diagram for your specific motor, try this:
remove the connection cover and take a look at the wires inside. Your motor
will have a "start" winding and a "run winding." Reversible motors are
tradionally reversed by swapping the connection to the start winding.
(Electrically speaking, swapping connections to the run winding would also
work, but often one of the run winding connections is not accessible.) Usually
the run windings, will be a larger size than the start windings. If you see
a couple terminals or wire nuts connecting to these smaller windings, swapping
them will reverse the motor direction.
I know this may be daunting for someone with no electrical experience, so
you may want to have someone more knowledgable check it or do some research
on in the web and check some pictures. Should be pretty easy to find examples
in google images.
There are no stupid questions, but there are lots of stupid answers.
