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 with them locking, 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,

Take the plug apart on the trailer and repair the shorted out wires. Better yet, go to the parts store, buy you a new plug (less that $10.00) and wire it according to this diagram..... On your "SHOOP" trailer.
