Toad vehicle turn signals not working

If they worked before but have stopped, check the fuse bank. After years, our toad's turn signals stopped working when on the coach, but both coach and toad worked fine alone. It turns out on my Holiday Rambler there is a separate fuse for each turn signal line going to the toad connection. Not sure why they blew, but the shop suggested I check for these fuses when I described the problem. Found the fuses, replaced and everything has been fine for the past year.
