trailer wire question
I had working brake and signals on both of my trailers and now niether, bulbs are good and they work on other trucks. I checked the power at the seven pin and found full juice for running lights but low amperage or whatever on the turn/brake pins. Could this be why I am not getting brake or turn lights on my trailers. Thanks.

The IPM (sp?, may be wrong acronym) is a known weak link for trailer electrical problems. It appears to be transistor switch (assuming, no hard fact) at this point, with not enough fuse protection. Some have talked about a relay box to fix the problem.
You may need to have the dealer fix it.
