Tscu rebuilding

[cal_look_zero]

Not to threadjack, but I went around the TSCU and spent less than $10. Manual cancelling, but at least I have reliable blinkers...

Sounds just like what he's after, pray tell him how to do it!

[chuck hahn]

Well seeing that i can get a truckload of chickens teeth easier than i can get a working TSCU and the fact that they are obsolete. I think that if someone can rebuild these even at say 100.00 or so its still a bargain.

[chuck hahn]

Yes tell us ALL how, its done and maybe post a wiring bypassing diagram..

[cal_look_zero]

Working on it as we speak.

And my switch self centers, so I had to eliminate that by removing this spring...



Basically, you cut off the end of the 4 pin plug, put female connectors on all 4 wires and attach them to the relays as indicated. The 6 pin connector can be taped over and zip tied out of the way.

I'm running all LED signals and they don't flash brightly unless the bike is running. Not sure how it will work with regular bulbs, but I have resistors on my signals to simulate an incandescent draw, so it should be ok.

Personally, I have always despised the self cancelling turn signals. I had one on my XS650E and it would cancel long before it needed to. It had both a timer and a distance calculator, and it would cancel while I was sitting in the turn lane in Dallas. The GS worked when I got it; it broke during a Fenimore rally. I never bothered to replace it even though Cycle Recycle probably has one. I don't miss it a bit. I only had 2 bikes that had them (out of +15) and I disagreed with the settings on both of them.

So "X" is the 4 wire FROM the wiring harness and "L" is the 4 wire from the TSCU...Correct??

[cal_look_zero]

No, X and L are marked on the flasher body near the terminals and indicate supply (X) and load (L). You completely remove the TSCU and use just the 4 pin plug. I'll snap a couple of real pictures when I get off work tonight.

The black/green and blue/black are the power supplies and the green (solid) and black (solid) are the feeders to the signals themselves. You can touch the wires together after you clip the plug off to see what goes where.

So theres 2 flasher units..one for each side.

Indeed. Simplest way I could think to do it. I may delve a little deeper at another point in time, but I was going for quick, cheap, and legal.

[chuck hahn]

I may take one apart and just use two small square ones from Autozone and hide them inside the emptied TSCU case..works and still "LOOKS" stock. Long as they flash on each side and stay reliable is all thats really needed. So may i ask what the 6 pin plug is for??

Note that some of these colours change through connectors but IIRC these were the colours in my harness

.

*** harness side of the wiring***

[chuck hahn]

If he says to just wrap and disconnect the 6 pin then i guess its really irrelivent to what i need to accomplish..I was just curious.

[sedelen]

Was thinking last night, if there was some way to wire in the second generation TSCU, that would be a blessing as they're reliable, fairly common, and not that expensive. A wiring diagram of the 1st and 2nd
would be a blessing and it would be easier to figure all that out, but all I can find is a block diagram depicting the unit.

Chuck, sorry the bad TSCU, Dale will take it from you to add to his mounting collection.
I may have another one that doesn't self cancel.
I've been searching for others out there but these things, bad or otherwise are getting hard to come by.
