New Build, Indicators and Flashers Stopped Working

[TN_Scooter]

This is a new build, 420S. After putting the battery in, I checked all the lights, flashers and indicators. Everything worked fine. On my first test drive around the neighborhood, I put the turn signal on at the second or third turn, Half-way through the turn, the beeping stopped. The turn signals stopped working. After getting back to the house, checked everything for loose connections but still no flashers or turn indicators. Took the car out today for a short test drive and the turn signal worked for about three flashes then again, no beeping and no flashers. Got back to the house and pulled all the fuses to see if any were burnt, all were fine. Open to any trouble-shooting ideas. Thanks to all for any help.

Do the Emergency flashers work? Just asking to take the relay out of question.

The emergency flashers do not work (they did during initial testing). Not sure which relay to pull. Looks like there are six of them under the dash.

I just blew a fuse replacing a 3rd brake light wired into the flashers on my new build 420.  My fuses are flipped but in this order (washer fuse is the bottom).  This should orientate you for the flasher relay.  
 

 

the flasher unit 10amp was the fuse that burned out for me

CBuff,

this is great, Could not find the fuse layout anywhere. This will give me a good starting point. Thanks!

Just a quick update, I pulled the relay and the fuses. Tested all, they were good. Plugged all back in and the flashers / indicators have worked every time I tried them since. Still not sure what the issue was but am happy that everything is working.

If your switches are like mine: (simplified version)…

all connections go through hazard switch. After switch is activated there is often a bad connection resulting in indicator light malfunction. 
cycling the switches on/off several times (probably rubbing off disuse oxidation) will restore normal function through the hazard switch.
