Hello out there fellow nortonians. My 74 850 stock roadster has me baffled. The left turn signaL ( FLASHER) works fine with no pilot lite on and with pilot lite on but only turns on but will not "flash" when the low or high beam headlite is on. I noticed that sometimes it will if the motor rpm's are high enough. Also, I noticed last nite while riding in 40 degree farenheit temperatures,that the right turn signals acted the same way until I reved the motor, ( this is the first the right ever acted this way) but the left refused to flash at all even when I reved the motor. What do you think???? Captain

As little as possible, but I solved similar symptoms by replacing the flasher unit with a cheap unit from the local auto parts store. Couple of bucks at Shucks vs. $12 from Andover. Had to massage the new round unit into the rectangular holder (round peg in a square hole so to speak), but it solved the problem.

Careful about installing the round flasher unit in to the rectangular holder... I did that last Summer and the corner of the flasher holder rubbed through the insulation on the rectifier. It cut the output to about 1 amp. The Charge lamp never came on as the voltage was correct, but the engine began misfiring and ran worse and worse. Happened to be nearly dark when I took the seat off and start looking for the problem... Then I saw the tiny spark arcing between one of the rectifier plates and the turn signal flasher mount. Put the flasher on with a tie wrap and a dab or RTV on the rectifier and was good to go.
Check the turn signal plastic bodies for a good ground... you know it is 'supposed' to ground THROUGH the plating on the plastic. A proper ground wire from the bulb mount back to the ground wire in the harness is a proper fix.
Now if the turn signal switch were placed so you could actually use it with out having a double jointed thumb you could stop using hand signals.
The hot ticket would be the LED turn signals and brake lamp and the SPARX left hand switch controls.
Ho Ho Ho, or else! Orlin

Orlin I feel is on the right track in regard to earthing.
Earthing will lead ~ or NOT ~ lead to some very strange problems all round..
I agree, most of your problem is earthing.
I guess it is all about whether you want to retain originality on your bike as to whether you start replacing the original flasher stems.
I agree they are right sods of things and its only through perseverance that I still have the original Lucas stems.
