Title: Left side blinkers quit
Post by: Mhanis on January 24, 2018, 01:30:11 PM
I noticed on the way home yesterday. They are Ducati Performance and have been on for a few years. The dash still shows blinking however.

Do the two sides (left and right) have their own fuse or are all 4 run through a single fuse?

I'd pull my wiring schematic but I wouldn't understand it.  [bang]

Thanks fellas!

Year and model?

Your owner's manual has a fuse box page (to check the one or two question)

According to the manual, only one fuse. Unless I read it wrong that fuse is also shared with the headlight.

Well the headlight is just fine.

Seems I'll have to start taking things apart and looking around.

Loose/bad ground to indicator common.

I have no familiarity with the DP blinkers on your bike, so, first some questions.

   Are they LED?
   If so, did you install them?
   Are the resistors separate or part of the blinkers?

Now for the generic part.
   Is there power to the units?  If so, how many volts?
   Are the grounds good?  With an ohmmeter you should have continuity from the ground wire to ground.

Shade tree no meter quick check:
   Swap a left side blinker to the right.  Does it now blink?

The DP blinkers are LED, each signal has a resistor that plugs into the OEM wiring harness and the blinker into the resistor. I'll shoot a photo when I take stuff apart.

I have an ohmmeter so I'll prod around.

Good idea about switching blinkers from side to side.

Well, I should have looked before posting because wires have simply come detached from the wire connectors on BOTH left side blinkers. What a coincidence, especially considering I just had the bike inspected less than a month ago. I am not real impressed with the DP blinker build quality. This is the second and third time this has happened. Had it simply been ONE blinker this is what I would have thought of first, but when they both went out so close together I assumed something else was up.

These are tiny little wires, we'll see how nimble my rather untalented fingers are tomorrow.

Thanks bruthas!

Pardon the Hoppes #9 stained 1911 schematic.

So this is what the resistor looks like:

The part on top is what plugs into the OE wiring harness. The female connectors at the bottom are where the blinker plugs into the resistor. The male connector on the right is where they have come apart.

(http://i261.photobucket.com/albums/ii44/mhanis-colt/20180127_162719.jpg) (http://s261.photobucket.com/user/mhanis-colt/media/20180127_162719.jpg.html)

If you look closely at the end of the black wire you can see that the wires are not coming out of the connector, they are breaking off where the connector is crimped. I peeled back a bit more of the insulation and put new male connectors on. The new ones (not photographed) have some heat shrink at the end so maybe the bit of extra support will help this from happening again.

Funny related story; see how the resistor has a black and a red wire coming out of it? And the blinker has a black and a red wire coming out of it too so one would assume black to black and red to red, right? Not so! When I first hooked these up a few years ago I connected them color to color and they didn't work. Frustrated I looked at the wires and thought "Could it be?" Yes indeed, black to red and red to black. ALL OF THEM.

They work now, I'm happy.

;D

That is some underwhelming work.  Looks home made.

I couldn't agree more Howie. These are sold in pairs and I have had to buy 3 pair so far because on one of the previous failures the wires became detached from the "motherboard" or whatever it is called inside the blinker. I can do ham-fisted stuff like put another connector on, I cannot in any way re-solder something that small!

Another failure and I'll go to something else all together, even if that means cutting the OE connector. Shit, I have 55,000 miles on that joker I don't have to worry about resale!!
