Turn signals all working with auto cancelling singalminder, until it didnt...
Right rear directional has no power at all.  
Fronts seem to be very bright.
Is it 1157 bulbs for front and 1156 for rears ?
Can the signal minder easily be removed and rewired back to the same OEM ?
I can cancel my own signals.
Thanks again, everyone.

I'm an idiot and forget to cancel them half the time.  It's pretty irritating to discover they've been on for five minutes.   :tickedoff:

So I use hand signals for most turns, except for occasions when my safety requires I broadcast the turn to traffic.  When I do, I try to remember to cover the button with my thumb so I don't forget.

When I installed mine, it came complete with mates for the harness connectors, so the mod can be reversed easily. Just unplug, connect the harness OEM style, and done.

Mine is actually called SigEnhancer by GCAT. I have a pdf of the install instructions, if you think that can help.

And, yes, 1157 front, 1156 rear.

I have ST2 auto shut off but I have yet to install but I'm selling the Valk thus not installing. As matter fact I'm going return it to stock as $3500 seems to be the going rate. The accessories are more valuable to other riders and included is hard to find OEM rack.

Could be something very simple. Take off the right side cover. Find the wire harness that goes to the rear lights. They should be in a opaque cover. The Lt. Blue connection to the right rear light might have become disconnected. The SM3 usually connects to the wiring using Scotch connectors which are notorious for cutting through wire strands. It could also be a bad connection at the top of the rear wheel where the rear light assemble connects to the bike.  I fought mine for years, always chasing down connection problems. The last straw was when the element in front turn signal bulb broke and shorted out . This caused a massive problem in the SM3.  finally took it out and went back to the stock turn signal relay. IMO, not worth the hassle.
