I recently bought a slightly used thumper that had been laid over once. They dented the tank and broke the turn signals. I replaced the factory signals with LED'S. Both front running lights work, rear signals work fine but only the front right turn signal works. The indicator light on the tank blinks correctly. Any suggestions on where to start searching for the problem?

Simplest test I can think of is
Put voltage on the one that don't wurk.
