My TSM went bad, I know for a fact it did, went I changed the handlebars the wire shorted and it didn't work ever since. That was about 2 years ago, and I survived with no turn signals for that long. Now I was doing some research and found out that it is possible to substitute the turn signal module with a simple relay, which would give you the difference to have to hold down the switch to operate the turn signals, which would be great! What I couldn't find is how to practically do it. An explanation from somebody that did that, or even better a wiring diagram would be awesome. The bike is a 1988 FLSTC.
