weird problem
alright lads, today i went work and noticed my indicators wasnt coming on when i asked them too, i flicked the switch left and right and nothing, anyway on the way back from work i noticed that they only worked when i stopped :?: , ok.. , ive never come across a problem like it before, my battery is charged and ive got no loose wires and it doesnt make a difference which way my handle bars are so i can rule of switch gear wire fault, its only when i come to a COMPLETE stop they come back on, they work if i stop turn them on and drive but if i turn them off and try them again when driving they wont come on untill i stop, any one heard out like it before??

That's a new one. I'm guessing a bad ground.

While moving at a good clip, pull in the clutch and let the engine go to idle with the signal on...does it work then? When stopped, is the brake light on when they are working? I'm thinking a bad ground or crossed wire somewhere. Could be voltage related if the 1st experiment works. No real ideas, never saw that, ever... Bill R |

My theory is the ground is lost as others have said. The blinkers are borrowing a ground path when the brake circuit is energised. Not a clue exactly where to start looking though.

electrical problems are nightmares, and a huge PITA to deal with. but most times ive had electrical problems, its the stupidest smallest problem. i had one on my old mustang that a few strands of wires got pulled out of the connection and under acceleration when the motor would move the wires would hit the body and cause a weird issue..

i checked all the wires i could possibly find and everything was as it should be, i tried a different rely and replaced bulbs but nothing, i did find that when my bike sits on idle then i rev it with the indictors on SOMETIMES they wont flash for 2-3 seconds untill the rev's drop back to idle speed so my guess is my stator and that its struggling to somewhat produce a steady flow of electricity BUT its not effecting my headlight,side light or brake lights which all work fine even when my idicators die, im really confused on this, im going to buy led flashers and a relay and see what happends then, p.s all my grounds are fine and ive scratched the lead blocks on the battery just in case
to billR: My bikes a sinnis apache aka qingqi 125 supermoto, yes when driving any speed if i pull my clutch in with the signals on they WILL come on when my revs drop to idle, my brake light works absolutely fine even when my indicators arnt, ive checked my grounds and cant find any bad ones any ideas? |

bennell,
Do you have a volt meter that you can put on the battery terminals? Try turning the turn signals on and measuring the voltage at idle and the voltage when you rev the engine and the turn signals stop working. The above test will see if a big voltage drop or big voltage gain is occurring when you rev the engine. You should read about 12.5 volts at idle and about 14 volts at higher rpm if the stator, regulator,etc is working correctly. |

You have a similar problem to one I was seeing on my headlight. My GY-200 had the headlight wired directly to the stator output for some strange reason. Whenever the battery took a full charge and the rectifier started dumping volts, the headlight dimmed. Put a load on the battery, bright headlight??? Never did sort it out, just hooked the light directly to the battery and all was good. Trace the wires from the blinker relay and see where they hook up into the harness. Is there a point where you can unplug them and hook a direct feed to the battery? If so, do that and see if the problem resolves. Also, check the voltage at the battery with the bike idling and at about 3-4k rpm. You should see around 13-14 volts, much lower or higher, then you start thinking bad stator. Welcome to the world of "electrical gremlins" :twisted: Good luck and keep us posted. Bill R |

i tried the headlight trick and it worked, i drained my battery as much as i could last night and tested it this morning but it still didnt fix it but as soon as i stuck my headlight on the indicators worked spot on? weird one. ill buy a new rectifier and relay see if it sorts it out for once and all,
thanks pal |

I made the switch of both parts on mine and still had the issue (because of the wiring, which I found after the fact :? ). It may be cheaper and simpler to just run a direct feed from the battery to the flasher unit. Bill R |

Without knowing what the voltage is...it sounds like something in the signal circuit is getting high voltage from the stator. Maybe causing the flasher to stop working. Can you find the wire feeding voltage to the signal flasher? If so, unplug that from the harness, if possible and run a jumper from the battery positive terminal to the flasher. Go for a ride and see if you have the problem. If that can't be done, take the flasher relay out and see if you can find a replacement. Maybe something wrong in that piece. I'd be at the same point if it was mine. Electrical problems are headaches. Good Luck Bill R |
