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,
-luigi
