Indicator help

Hey all,

Recently out of nowhere my right turn signal has stopped working. When the switch is turned right nothing happens, left wide works fine.

When turned right:
-The dashboard does not show an indicator is being used
-no lights turn on
-literally nothing happens

When turned left:
-Dashboard shows an indicator is on
-Indicator is on and blinking

I have never crashed or anything, this happened the day after some hard riding but the indicators worked when coming back from said riding so I do not think the events are related.

Does anyone know what part I may need to replace/what is wrong

Hi Sean! Welcome to Ninjette!

Let's see if we can get you fixed up. First measure parts to determine if they are indeed defective before replacing. Otherwise you will be replacing perfectly-working parts with brand-new perfectly working parts and nothing changes. Which is waste of time and money.

1. Measure continuity/resistance of turn-signal switch in left-turn position (orange + green)
2. Measure continuity/resistance of turn-signal switch in right-turn position. (orange + grey)

If they are not same measurement of 0-ohms/continuity, switch may have damage or corrosion. It can be disassembled and contacts cleaned. I use 9x9 baking tin to do this surgery as 27 tiny ball-bearings of 5 different sizes and 52 micro-springs will fall out when switch is taken apart. I don't recommend doing this unless you really know what you're doing.

Next step after testing switch, and if OK, is to measure wiring between switch and flasher-relay. Then between relay and bulbs. Most of time, if is switch OK, it's in wiring. A lot of time people replace flasher-relay and bulbs to no effect because they're fine.
