Maybe I have to take off main cables from batteries to starter..the connections are clean at the ends, but is it possible corrosion somewhere in the middle of cable?

I drove a 1997 international with a 2012 wilson trailer, Now we got newer used trucks. I have a 2009 frieghtliner with the same trailer and the trailer locks-up. if I turn the key off the abs works fine, With the key on The tires lock. Can anyone help me? Thanks, Jeff

Running, are there any other warning signs like a trailer ABS light on the trailer or instrument panel? If no warning lights then make sure key on that you have power on the center pin (pin 7) of you pigtail connector. No power, check the fuse.
I would double check your brake adjustment. -
Check your ECU line from ecu to battery. Something similar happened to me this week ..when you turn your key and and let all your gauges cycle, check to see if your check engine/stop engine light comes on and cycles ..if it does not, its ecu related .the wire, or ecu itself ..

I have no dash Icons on. The abs light on the trailer comes on for about a second or two when I apply the brakes then it goes out with the key off, I can roll and the wheels do not lock. When the key is on I repeat the process and drag my tires. (pin 7) has power to it with the key on. All my lights come on then go out after engine is started like they should. I am thinking about disconnecting the wire to pin 7. If anyone has any other ideas please let me know. Thanks, Jeff
