Unfortunately you have not given us much information to go on.
Lots of obvious things to check, starting with all the wiring connections and verifying that the engine is turning the dynamo.
Next check the output before the regulator if there is output move on to the regulator.
Lots of useful information on this website which should help you trace the problem;
