i have a 2012 T800 with a ISX.
The turn signals only work with the dome light on.
Flashers work fine on their own, all the market lights and head/ tail lights work with the dome off.
I replaced the module on the steering colum, i have a good ground there.
When i put a test light on the wires, i have power all the time on all the wires coming out of the module, with the dome on and off.
I have a good ground at the light.
I'm beating my head against the wall with this thing, if i knew where to jump a wire, i would!
Any help would be appreciated
