I have a new boat trailer 5pole also trailer brakes.All worked fine for a few weeks. One night while backing up boat trailer noticed only brake lights were working. was in hurry so unhooked and left. Next day hooked trailer back up to truck and only had left side brake and turn signal. Needing to leave I hooked it to second truck turned on headlights all lights on trailer came on and imediatly went off again with same brake and turn signal only thing working. Then was stupid and hooked to third vehicle same results. Then hooked up all three vehicles to utiliy trailer and nothing worked right . I am sure there are blown fuses but what would cause this. Thanks
