My trailer and truck were great. Then all of a sudden things got weird. The break light fuse and blinker fuse blow when the trailer is hooked up. Any ideas /
Also why do my flashers not work when the brake lights are on?
Everyhting was so good for a long time.

Sounds to me you have a short not a grounding problem. Not sure what you are pulling with but if I where to guess you have yellow turn signals. If that is the case your isulator box is bad.

Indeed the fuses blowing were due to a loose wire in the plug on the trailer side.
Any thoughts on the flasher deal. They did work for one day as wired now . The problem is when the flashers are on and I step on the brake they stop flashing .

When you say flashers do you mean emergency flashers or turn signals? My emergency flashers stop flashing when I have my foot on the brake on my 85 F150 regardless of whether I am towing or not.

Yes I do mean the emergency flashers. Are they supposed stop blinking when the brake is on. It does this with and without the trailer

Greg, I don't know how many year models did this (I think the later year models keep on flashing). But stepping on the brakes stops my emergency flashers from blinking on my 85. Does it on my 85 Corvette and 82 280Z too. I can't give you the techical reason why but horsepuller's explanation makes sense. What model truck do you have?

A kind of related topic.
On a 1969 F-100 I had once, when the emergency flashers and a turn signal were both on, holding the brake on would supply power to the radio. I saw it on one other 69 Ford truck also.
