Auto-cancel

[jsandidge]

Everything on my bike works, except for one thing. I have to manually cancel the turn signals. What should I do to trouble shoot this issue? Manually cancelling isn't a big issue to me, but I really want everything to work. Any ideas are appreciated, thanks.

There's a reed switch on the speedo that needs to be working. I've seen some that had the glass tube broken. Also make sure that the relay wasn't changed out with the two prong automotive type. Using those will work allow the lights to flash but will disable the auto-cancel feature.

Inside?

I'll check that relay. As for the reed switch, is it inside the speedo housing?

It's attached to the outside of the speedo housing.

Most likely you need a new TSCU. They fail sometimes. You can find them for cheap on ebay or maybe post in the WTB forum. They are a common part servicing several models so you can find them easily enough.

Aftermarket turn signals or bulbs can cause this problem using different watt bulbs. They have to be correct or they won't pulse so folks put in an automotive relay. Make sure this is not the issue first.
If it is not the issue I have good TSCU boxes.

Thanks guys

Thanks everyone. I'll check all this stuff tomorrow first, and if it is the TSCU, I'll send you a pm chef.

What a dummy - me

Well, can't blame everything on the PO. Over the winter, I replaced a bunch of wiring connectors. Turns out, I mixed up the wires on the harness side of the TSCU. Swapped them back around to the correct slots and BINGO! Everything works as it should. Now I have an extra TSCU if anyone needs one.

Yep

I think that's the problem, almost for sure. I've changed mine twice and always keep a spare for when it happens again.

Just as a matter of interest, I've noticed that they don't quit working all at once. They seem to work sporadically before 'giving out' completely.

I hate that feature. Before I bypassed mine on my 850, I had them cancel more than once while I was waiting to make a left hand turn. NOT kosher...

I've never had that happen with the 2nd generation TSCU. Failure with those is they don't cancel, not cancel too early.

Maybe I signaled too quick... or there was tons of traffic

Only one I've ever had was on my '83 model.
