Have the NRC signals front and back, the front right stopped working a month ago, sent email to NRC and they sent me a new one no questions asked, plugged in new one today now both fronts not working, rear signals both work no problem, any ideas what could be wrong?

you can use a cheap test light. The NRC should have ground an power wires for for each turn signal. Your bike has a left and right turn signal light wire. Go to the left side, turn the signal light on then clip the clamp of the test light to a ground. Could be the engine. then with the point of the test light touch one of the turn signal wires and see if the test light lights up and flashes. I'm not sure which is going to the the positive wire but if the test light is grounded to the engine you should be able to test each wire. Once the light flashes you know you have the + and you know the issue isn't the bike. If neither wire makes the test light flash then you will need to check the fuses. Actually check the fuses first.
