Hi all,
jonway madness yy50qt-31.
i have a currently annoying problem and I keep thinking i fixed it then it rears its ugly intermittent head...
when i switch off the key the engine keeps running, all the lights dash fuel gauge etc go off so it appears the ignition switch is working. Now I know one of the things to check is the earth wire for the cdi I have a side stand cut out and that works so that tells me the cdi and the wires to it are fine. I don't have a kill switch on the dash like some scoots just a side stand cut out and ignition.
there are 2 red wires under my seat the main ones from the battery, I will show you an image, now when I was moving the wires in that area then engine would cut out as it should so it's a loose wire or broken wire somewhere I just can't find it. I spent ages and it seemed as though the connection onto the starter solonoid was intermittent so I chopped an inch off and replaced the end re-installed and all was good while it was still, went for a ride came back and bam issue back again, I'm hoping someone with good electrical knowledge of the gy6 harness can point me in the right direction so I can try and find the culprit wire. Now some info to help with your diagnosis.
while the key is off I can still kick start the engine so it's acting as if the ignition is un-hooked (I can 100% confirm the ignition is working fine and the wires connecting to it are as I have chopped and re ended them tested with multi meter all working as it should) so I think there must be a break further into the harness (somewhere near under the seat as per before) I do have an alarm system with remote start yes I have presses the unlock button and it doesn't kill the engine. I have started it with the fob but again pressing the unlock key does not stop the engine only the side stand does. I have removed the alarm system and put a bridge on it as per other threads I have found this does not solve my problem. Any help appreciated.
on another note fuse blew and I was reading 18v at the headlights so think my rectifier is broken, I have replaced and all is good again with that now just wondering if a connector somewhere might have been burnt out or a wire. I have stripped the bike back to the frame trying to sort this and replaced most of the spade terminals and connector blocks can't find any culprit seems like it's a break in a wire somewhere.
can someone using the above info work out which wire or part of the harness I need to look at, again to summarise, key off engine continues to run, if I kill it with the side stand I can again start it by the kick start while the key is off, all lights dash fuel gauge etc are off while key is off as they should be they come on when I turn the key on
long post but hopefully enough info for someone to help bring back my sanity intermittent issues really are the worst!!!
