So before to put everything back together, I decided to check my lights and so on...
I had some intermittent problem with my turn signal and now it seems to be there for good.
The 4 way flasher was staying stuck so I decided to open the handle (2 screws only) and spray some contact cleaner on both set of switches.
The flashers were working, going on and off nice. It also confirmed that the signal lights are all working.
Went back to the shop this working and the flashers are back as it was, getting stuck. I sprayed the inside with contact cleaner again and it did free it up... Sounds like I need to take it apart and do a proper cleaning!
The turn signal are also behaving erratically. When you push the lever, either way makes no differences, nothing much happen. Sometime if you hold it long enough you can hear the relay trying to stick and it makes a buzzing noise while the lights blink rapidly...
Question:
Is there a way to determine if the switches/detents in the handle are working or if it is coming from cancel unit itself?
I found this "How to" in another forum, to bypass the TSCC unit. Would this be applicable to my 1990 SE? I am old school and could easily live without it

If I need to open the handle deeper then it is now, how can I remove the choke cable at the handle end. Does the air box has to come completely off to get to the cable clamp and get enough cable slack on the carb end of it?
Cheers.
