I am having problems with my toad lights. I have tail lights but I don't have turn signals or brake lights. I ran over a 5 gallon plastic bucket

and cut my cord (not all the way through) from my motorhome to my toad. I have repaired the my cord, It blew the fuses for my coach's lights. I replaced the fuses and all the lights work on my coach. I have checked the hitch and all is good there. I plug in the cord and have RH turn signal at the end of the cord but my tail light turn signal still isn't working. I'm not getting the LH signal at the end of the cord. Any thoughts?? Could my ground be bad on my toad lights. BTW the toad lights are a separate system. Worst case I can rewire the toad
