Check the bulbs and see if they are good. Ask the guy if they worked prior to you gettin it. If the regulator is bad it would either pop the bulbs or not run anything considering it wouldnt get the juice to the coil.

If not the regulator, it has a lighting coil under the flywheel. It should read an AC voltage (30-40V) that gets switched to 12VDC at the regulator. Check voltage out of the engine to see if it's OK.
