What are the symptoms on a bad relay switch on a 1973 FLH? Where is it located?

Usually a clicking noise or sticking closed so the starter doesn't stop when the button is released. Although there are several causes of these symptoms, so a full diagnostics is in order. Start with the battery, even if is is fairly new. Then check for voltage drop across the wire and relay under a load.

The original location of the relay is under the bottom of the battery box. Although I've seen 73 FLH with both the Ford and rectangular type relay.

Check cable connection points and ALL ground wires to frame, they are notorious for causing multiple electrical issues.
