I have a 79 that I bought with no rear turning signals. It has fronts, but they don't flash.
Would the front ones be dependent on the rears? I've never had access to another set to test them.

The XS's front and rear turn signals are wired together, but that may not be the simplest problem. The flasher unit on the XS is very sensitive to current draw to make the lights flash properly. If the wrong bulbs are installed (or if any are missing, as it sounds like is the case with yours), the whole system can do screwy things. To ensure you have the right bulbs, make sure they are 27 watt bulbs..... Of course, they are standard 1156 bases, and yeah - if you want to be original, you'll need all 4 of them to make it work.
The other option is to get a different flasher unit. I've converted my whole bike to LED's - which have almost no current draw, so the original flasher doesn't work at all, so I had to convert to a flasher that is compatible with LED's. Check in some of the other threads and there are some mentioned.

Like Norm said, the flasher unit works on the current draw. In laymen termss... Current passes through it, it sees the current draw and turns on, then it sees a draw on power and turns off, then it sees that current is being passed to it and turns on again, then sees the draw and turns off... so on and so on, so it flashes. I believe it's similar to a heat switch on a toaster, enough power goes through and gets hot enough and a switch flips... So if your draw is low, like you only have one bulb hooked up and working, it doesn't see enough draw to turn off and the one bulb just stays lit. When your battery is low you might see something like this, or very slow flashing. When I was questioning wether my flasher was working, I wired my headlight to it to test... The thinking here is that if there is one light bulb I know that draws a lot of juice, it would be the headlight. Also, having a cheap multimeter tester handy helps.. Harbor Freight has a coupon for $2.99 right now for one. I'm on my second one right now because the first one flew off my bike at 50 mph  it was duct tapped to my handle bars when I was testing my charging system. |

Grepper, Harbor Freight sells a voltmeter that with a mount works good. I built a mount out of sheet metal. It mounts to the risers. Hold the meter about where the stock switch was. That way you won't need duct tape.
