Help.

I'm the original owner of a 1998 Shupe 2 horse bumper pull with a 7-pin round connector.

Recently, when we hook the trailer to the 7-pin connector and try to pull the trailer the brakes lock.

I can pull it without the connector, but that means no lights and no brakes -- a bit unsafe at best.

I have another vehicle which I tow with and get the same results so it must be in the traier.

I recently replaced the emergency break-away switch and same symptoms.

Would a cut in the electrical line (or something causing a short) be a cause for this type of symptom?

Any suggestions would be greatly appreciated.

Thanks,

-luigi

You are getting power to your trailer brake terminal (pin) for some reason when you plug the trailer plug into your tow vehicle.  If you are using a 7 to 6 adapter, check it as it could be cracked on the inside & might need to be replaced. If you are not using an adapter, your trailer plug may be cracked inside or it has power jumping from one terminal to the other inside the plug. If you are not knowledgeable on the electrical side of trailer brakes, have a qualified trailer mechanic check it for you.

Good luck.

Your problem is the hot wire and brake wire is crossed. Usually the problem is in the plug. On a 7 way plug, it is the black and blue positions that need to be switched
