Take a volt meter and check the plug. If the plug has power, plug back in and check the TM. IF you still have nothing, you have narrowed it down to the TM. Plug the TM plug apart and make sure that a wire hasn't backed off. If it looks ok, then you could have a TM issue that needs addressed. Better a TM issue, than a boat issue.
