one question i was just thinkin of... so you put the diodes in place to prevent back feeding from the 1 indicator light, what happens when you turn on the hazards and they're both feeding the one light? wont 2 12v power sources blow somethin out, like a fuse or even the indicator bulb?
The way I see your indicator only blinking on the right side, I'm taking it that you only have one indicator light for both right and left sigs. If that is the case you will need two diodes. That is a "check valve" for electric current. Take a wire from both sigs, you already have one for the right and put a diode on the end of each wire, hook them together and run one wire from those to the indictor light. Done. The diodes are very small and you will have to ask the person in Radio shack which way the current flows and which way it is blocked. Hope this helps. Ride safe.
so to dig the thread up... ive tried everything with my speedo to get my turn indicator to work with both lights. my bike came from the factory with 1 light for the 2 turn signals. ive followed the wiring diagram as closely as possible, ive switched wires around, and no matter what, still cannot the indicator to work on both signals. any ideas? if the factory indicator was 1 light, shouldnt this one plug in just the same?
