    Turn Signal Wiring Help

    Howdy All. I bought a new set of 4 turn signals that have 3 wires: red, black with white and black. I can't figure out how to hook them up. I've tried all the combinations and they don't want to work. The stock signals worked fine, so I know its not a power issue. There are only 4 connectors for the turn signals in the headlight bucket: 2 grey, 1 black and 1 black with white. Does anybody have any idea where these new turn signal wires go? Thanks.

    The black wire with your new signals is an extra, just leave it. Follow your wiring diagram but basically the B/W goes to your B/W and the other goes to the power wire for that side signal.

      Hi,

      Are the new bulbs single filament or dual filament?


      Thank you for your indulgence,

        IF they are some type of LED's you need to change the flasher to an electronic one !!

          They are not LEDs, but they are dual filament bulbs (running lights and turn signals).

            Hi,

            Are they also the same value, 12v 23w/8w Stanley #1034 (or generic 1057-ish) as the stock bulbs?

              Gee, that I don't know. I'll have to investigate that one.

                Make sure they are grounded
                The B is hot
                B/W is ground
                The R is running lights (hook into a switched hot wire)

                  Most turn signal stalks are mounted in rubber bushing and aren't grounded (some, not all) so you may need to use that extra ground wire to ground them. Get yourself a circuit tester ( one of those jobbies that has the light) and start testing and isolate the R/L turn signal connections and the switched hot wire for the running lights. Then connect your wires accordingly.

                  I know when I went to the running lights on my bike I had to use the extra ground wire to make it all work.

                    Thanks to every one for all your help. I can rebuild carbs, master cylinders and brake calipers, but when it comes to electrical, I have no idea what I'm doing.

                      Did you get them working correctly?

                        Unfortunately no, I never could. I ordered a set of single filament 2 wire signals, so those should work just fine. I hope!
