Ok.....here goes.....My father in law got me a set of directional signals from the local Triumph dealer (Motorcycle Enthusiasts). They are 2 wire (Yellow and Black), universal. I have the wiring diagram for the 1982 Honda CB900 Custom, in detail, clear, and in color. I can read a wiring schematic, so I began assembling the bucket. I ordered an original LEFT HAND control off of eBay ($12.50), as the original was previously damaged, and the Suzuki one I was going to use was rather complex (I wanted the ability to turn on/off the headlight). So, going with the "Plug and Play" option, I plugged the main harness in, plugged in the headlamp, and turned the key. Headlight functions properly (on, lo/hi). Then I begin hooking up the directional signals. Out of the pigtail from the switch, I connect the Yellow directional wire to the factory Orange/White (O/W) stripped wire. The black wire to the solid Orange wire (O) that runs to the indicator/rear Directional light. I turn on the key. Both lights light up as running lights. I hit the switch to "blink". The rear blinks. The front light goes out. I turn the switch off, and both come back to running lights.
This happens with BOTH right/left directionals. Now, this bike had originally been fitted with a Vetter fairing. The Vetter fairing wiring harness was removed and wiring exposed.
I am wondering about a possible ground? On the factory wiring diagram, it shows all 4 directionals grounded. If that is the case, then the rear directional are grounded by affixing to the frame/bobbed fender. The front go through the bucked mounting brackets, a metal sleeve that sits inside a rubber grommet that is held in place by a nut, against a washer, against the rubber grommet.
When I look at the main harness, I see a Green Ground Wire with 3 female wire connections in a line. Now, the rear had this same set up, except it had 4, 2 to the rear light, 1 to each directional. I was able to add a ground wire to the new tail light and plug that in. Remember, this had a Vetter fairing, so I do not know what the original factory lights/connections looked like. I am wondering .......... Do I need to hook up a ground wire to each FRONT directional for them to blink? Like I said, there are only 2 wires on the aftermarket directionals, and the rear do blink.
I did reverse the wires to see if that changed anything, and it did not. Rear R/L blink, then return to running lights when switch is off. Front R/L go out when turned to "blink", then return as running lights. Lastly, voltage and continuity were checked. When a light tester was applied to the O and B wires that run to the back from the headlight bucket, the light tester did flash. Just cannot figure out why the 2 front will NOT flash........
