Turn signal controller

If you are speaking of 1980-up controllers; contact Highway_Glider. I'm 'sure' he has a working spare he might be willing to part with.

850 combat,
i have one pre 80 controller left(pretty sure) and several 80 and later left.
did you get one from me before?

So how far out are you guys from a viable replacement for the 78 1000 TSCUs???

Mine's ready now, electrically. I still need to address physical aspects like strain relief. It's tucked away in a nice little project box, and is way too big for what it does, but it's finished and it works as designed. I'll be wiring it into the GS1000 in the next week or two for actual street testing (Oooh, oooh! Such excitement!). The biggest headache? Strain relief. Connecting the nice fat OEM harness pigtail to those tiny little header leads from my perfboard.

The IC's are socketed (so I can reprogram either PIC as needed to tweak its operation) so it's about twice as thick as it needs to be. Subsequent units can be shrunk substantially.

Mine at present is pretty highly tailored to what I plan to do, which is to swap in a pre-80 bar control into a 1981 GS1000 and have it self-cancel, as well as other shenanigans, without butchering the OEM wiring harness. The bar control won't plug in, obviously; instead, it'll be connected with Posi-Locks. The signals themselves will be connected the same way -- existing wiring + Posi-locks. This will automatically power the little bulbs in the instrument panel without getting in there.

The front signals will be fed with new wires so they can function as running lights -- nice bright LED arrays + a marker light for each side -- and they'll blink off, rather than on, at the same time that the rears do the opposite.

To answer a few other posts: I've never intended this as a replacement for an original TCU, but I've kept enough notes & diagrams that it could be adapted pretty easily for the pre-1980 setups.

I don't see much problem involved in designing a much simpler unit that would do what a lot of folks are asking for -- just blink. Just work. Inexpensive, no self-cancel, no extensive harness mods. A simple 08M2 and a pair of relays would do that and deal with the momentary nature of the bar switch. In other words: Push the control to the left, release, and the LH blinks until the rider presses the Cancel downward. Same with the RH side, obviously. A small subset of my unit would do that nicely.

That's what winter is all about.
