"Sticky," malfunctioning turn signal switch

[dave699]

The turn signal SWITCH on my 748 has become "sticky" and doesn't always want to positively click in and out of the left, right, and center detents. This means that occasionally it fails (more frequently on the "left" side) and I have to use the Mark 1, Mod 0 arm signals.

I popped the unit off my handlebar and lubed the switch with a dab of Tri-Flow (bicycle stuff), which was what I had at hand. It seemed to work a bit better last night on the commute home - we'll see how it does after sitting last night.

Besides just replacing the unit, does anyone have any guidance for what the issue might be? Unfortunately I don't have much time these days and I'd rather have a smart guess at what I'm looking for to fix before I tear it down.

Thanks!

Sounds like it's just dirty and may have a buildup of gunk inside. I don't know what the Ducati handbook would say but I'd disassemble the switch, clean it with the appropriate electrical cleaner solvent (isopropyl alcohol has worked for me in the past) and reassemble. Not sure if any lube or grease is req. on the pivot points but at least put some dialectic grease on the contacts.

On the other side of things, you can probably pick up a good used one for $40 if you look around.

Thanks. The quick disass, blow out, Tri-Flow routine seems to have worked.
