[SOLVED] Blinkers, horn and fuel gauge don't work

[50cc]

Hello everybody,

I have serious problems with the electrics of my scoot - all my blinkers and my horn don't work, all other lights work. It started yesterday. The bike had a real hard time kick-starting, then it did start (after I changed the spark plug), but was dying few times while idling. Speedo's fuel gauge is also not working. The blinker relay was just ticking REALLY fast, but no blinkers. Then suddenly blinkers started working (all bulbs were fine), so I managed to get home. This morning scoot started ok, I idled and throttled for half an hour to let the battery charge, but the blinkers didn't budge to function, the relay didn't make a sound. Headlight and brake light work.

I thought it was the battery since the temperatures here are below zero, so I took it home and measured it with my multimeter - looked great, 12,6 Volts! Anyway, I put it to charge, but the charger worked for half an hour then it displayed "FULLY CHARGED". I really don't know what to do.

Could this be a faulty blinker relay? Can a bad blinker relay affect the horn as well?

gotta be a relay or ground or something like that
JR is the best electric guy i know,
ally is up there a bit, but carbs are his #1

if u like reading diagrams and testing with ur multi.

Yes a bad Flasher Relay or a bad ground on the horn or Relay can effect the horn.

Thanks, Yosemite.

Update: Just an hour ago I re-installed my battery. Scoot started fine and now the fuel gauge moved, but only a hint above the red zone and I know I have a FULL tank. At first the blinker relay didn't make a sound, then I decided to try the horn. I heard a veeery low whining somewhere below the plastics, then I pressed the horn several times and it started honking like before, then I tried the blinkers and they also worked. Then I shut it off, went to get some groceries and tried again when I returned - no blinkers or horn again!!!!!! Same story as yesterday.. I think it's a loose wire somewhere or something shorts since it's very wet and cold here and I ride it in these conditions the whole winter, but I don't know where exactly to look for a bad wire.. Will it be the switch or the relay under the front plastic?

EDIT: Also, here I read it could be the ignition assembly (see last post). Is this possible?

If that is the case, (shorts due to dampness) might I then recommend CorrosionX?

If that scooter is like mine I just bought .You might want to look behind you dash and under your seat to see if ther are loose connections. In three weeks I have found loose starter selinoid wire, loose fuel valve ,fuel gauge wires loose as well. Mine has 4 phillips screws and the review mirror has to be unscrewed to seperate the dash from the steering column.These are somethings you may want to check.

Hi, thank you all! I found the problem - one of the cables of the 6-pin connector of the ignition assembly was torn. I removed both ends from the connector, welded them together and put some silicone and tape on top. Immediately fuel gauge jumped to FULL, blinkers and horn work like before!

The wire that was torn was red to red, low left on the female connector if someone else gets the same symptoms:



Thanks again, marking thread as SOLVED.
