My Kymco Miler 125 scooter indicators dont work. but my kill switch lights up the left hand turn signal on the dash display All wires are connected into correct plugs... im lost

One Side of the Turn Signal Lights Doesn't Work. ... You may be dealing with bad bulbs, a bad flasher relay, a faulty turn signal switch, or a bad wire or connector between the flasher unit and the turn signal switch.

check the ground wire, some where not even connected and install a pig tale to the battery to charge it on the scooter, if the wires are OK you need a new stater check with kymcoforum.com and look up bet and lose

check your switch. contacts could be not making contact. or your flasher unit is bad.

This information applies to the vast majority of Honda motorcycles. Colors for the right handlebar switch are: Grey sends power to the turn signal switch. Light Blue goes from the turn signal switch, to the right turn signals. Orange goes to the left turn signals. Light Green goes to the horn button.
The left handlebar switch: Yellow With Red stripe goes to the starter button. Black wires take power to the headlight switch and the kill switch. White goes to the headlight low beam, Blue to the high beam. Brown / White goes to the tail light, running and instrument lighting. Black / White comes from the kill switch and delivers power to the ignition coils.
I hope this helps.

your best try is to contact your dealer, and get them to order you the short red wire that runs from the + terminal on the battery, to the starter soleniod ( also has a thin red wire that runs to fuse holder) i had exactly the same problem and this solved it. i have however re done all the electrical connections on my bike using 7amp wire and bullet connectors, as i have had many faults with the electrics before.
My bike is a Kymco Cruiser 125 (almost exactly the same bike, i use kymco zing parts when replacing) i paid approx £16 GBP for the wire.
